Terms of Service

Effective date: 10 September 2026
Operator: Kaptra LLC (“Kaptra”, “we”, “us”)

Welcome to Kaptra. These Terms of Service (the “Terms”) are a binding agreement between you and Kaptra LLC governing your access to, registration for and use of the Kaptra website, console, API, documentation, software development tools, community and other related services (together, the “Service”).

Please read these Terms and the Kaptra Privacy Policy carefully before registering an account, obtaining an API key, topping up or calling the API. Clicking to agree, ticking a confirmation box or actually using the Service each counts as your having read, understood and accepted these documents. The passages in bold concern limitation of liability, disclaimers, unilateral changes, account handling and the treatment of balances. They matter materially to you; please read them with care. If you do not agree, please do not use the Service.

1. Parties and eligibility

1.1 The Service is provided and operated by Kaptra LLC. “Kaptra” on the website, in the console and in the documentation refers to Kaptra LLC and the service interfaces it authorises.

1.2 You must be at least 18 years old and have full legal capacity. If you use the Service on behalf of a company or organisation, you warrant that you are duly authorised and that the organisation is bound by these Terms. We do not provide accounts to minors; once we discover one, we disable the account and delete the information the law requires us to delete.

1.3 You warrant that your registration, payment and business information is true, accurate and complete, and you will update it promptly when it changes. Formal notices are given through console messages and the email address you have on file.

2. Definitions

“Account”: the user identity you create in the console, and the resources, orders and records under it.
“API key”: the access credential used to call the Service.
“Task”: one recognition or processing request you submit.
“Credits / balance”: the prepaid entitlement used to pay for successful tasks, measured in the units shown in the console.
“Successful task”: a task judged, under the technical documentation in force at the time, to have succeeded and returned a usable result. Tasks that fail, time out or are left incomplete by a platform-side error do not count.

3. The Service and your licence

3.1 Kaptra provides developers with API capabilities for captcha recognition and the return of verification results: recognition of image and text captchas, handling of interactive captchas, and returning the verification result into your calling flow, together with supporting features such as accounts, keys, balance queries and asynchronous callbacks. The task types, parameters and error codes supported are as set out in the developer documentation in force at the time.

3.2 The Service is provided as currently available. We may add, adjust or retire a task type. For material changes that may affect existing integrations we will give reasonable advance notice, normally no less than 30 days, except where security, compliance or force majeure requires urgent action.

3.3 Subject to your compliance with these Terms, Kaptra grants you a limited, non-exclusive, non-transferable, non-sublicensable and revocable licence to call the Service solely for your own lawful business. This licence transfers no rights in source code, model weights, datasets or the underlying infrastructure.

3.4 Recognition rates and latency depend on the task type, input quality, network conditions and changes to third-party pages. We cannot guarantee complete success or uninterrupted operation, nor that a given task type will remain usable on a particular third-party page over time. A scenario that temporarily cannot be recognised is not a breach on our part; because failed tasks are not charged, such cases do not in principle give rise to a refund.

4. Accounts and security

4.1 You must keep your login credentials and API keys safe and must not lend, rent or share them with unauthorised third parties. All calls, top-ups and operations under your account are treated as your own and are your responsibility.

4.2 We recommend using separate keys for separate environments and rotating them regularly, never exposing keys in front-end pages or public code repositories, and resetting a key and notifying us immediately when you notice anything unusual or a leak.

4.3 We may apply verification, rate limiting or freezing to unusual logins, unusual top-ups and unusual calls.

4.4 Without our prior written consent you may not transfer or sell your account, or resell or time-share the Service to the public at large. Where several projects within one organisation share an account, the account holder bears full responsibility for compliance and charges.

5. Acceptable use and legal boundaries

5.1 Kaptra provides recognition capabilities to developers to assist lawful processing of public information, automated testing and the automation of internal business processes. We expressly oppose, and will stop, any use of the Service for crime, fraud, infringement of the legitimate rights of others or disruption of network order, and we take a zero-tolerance approach to verified serious violations.

5.2 Provided you comply with applicable law, the target site’s authorisation and these Terms, you may use the Service for end-to-end testing and CI/CD pipelines, authorised process automation, collection and monitoring of lawfully public information, data retrieval or compliance checks expressly authorised by the rights holder, and similar scenarios. Collection of public information must respect the target site’s robots protocol and terms of service and must not exceed a reasonable access rate. Even with public data, obtaining it by defeating technical measures, breaching the target site’s terms or plainly exceeding a reasonable rate may still amount to unfair competition or another unlawful act.

5.3 Before calling the Service you must satisfy yourself that: your access to the target system or data is duly authorised or otherwise permitted by law; your conduct does not breach applicable cybersecurity, data protection, unfair competition or criminal law; the recognition results will not be used to harm the rights of others; the target is not a restricted target under Section 7; and, if you act for an organisation, you hold valid authorisation.

5.4 We do not review the legality of every target or business scenario you submit in advance, but we reserve the right to monitor, verify and act under these Terms. The absence of prior review is not an endorsement of, or guarantee for, the legality of your downstream business. You alone assess legality and bear full responsibility for it.

6. Prohibited conduct

You must not carry out, assist, organise or incite any of the following, including but not limited to:

6.1 Network attacks and system damage. Denial of service, traffic flooding, vulnerability exploitation or unauthorised penetration of any kind; using the Service to create security risks for third-party websites, interfaces or protection systems; distributing malware, backdoors, phishing pages or ransomware tools.

6.2 Identity theft and fraud. Credential stuffing, credential replay, brute-force attacks, account hijacking; bulk account registration or the creation of fake identities or fake content; bypassing or defeating identity verification, biometric checks or other security mechanisms; impersonating a person, an organisation or an official body for fraud, phishing or social engineering.

6.3 Violation of privacy and trade secrets. Scraping, reconstructing or selling non-public personal information, payment information, identity documents or communications; stealing trade secrets, undisclosed interface data or protected content that requires a login; circumventing access controls to obtain data you are not entitled to.

6.4 Abuse and disruption. Mass spam email, spam comments, spam registrations, SMS bombing or harassing messages; ad click fraud, fake traffic, inflated metrics or rankings; automated purchasing, ticket grabbing, flash-sale sniping, hoarding or scalping of scarce resources such as tickets, limited-edition goods or public appointments; game cheats and automated cheating; manipulating public opinion or interfering with elections; other automated abuse that seriously disrupts a third party’s normal business.

6.5 Abuse of the platform itself. Reselling, time-sharing or repackaging the Service for sale, or giving API keys to unauthorised third parties; bypassing billing, forging task status, farming bonus credits or promotional benefits; reverse engineering, probing, stress-hitting or countering the platform’s risk controls; any other conduct that may make us liable to third parties or seriously harm our reputation.

6.6 Other unlawful conduct. Breaching any law or regulatory requirement of your location, the location of the target business or the jurisdictions our operation is subject to; breaching a valid agreement with a third party in a way that leads to criminal or administrative liability or serious infringement.

7. Restricted targets

7.1 Whatever the purpose, you must not submit tasks against, or carry out automated access to, the following systems or platforms:

government agencies and public-service systems;
critical infrastructure, including energy, transport, water, telecommunications, core financial systems and public health;
online banking, payment, securities and credit-reference systems of financial institutions;
identity verification and number systems of telecommunications carriers;
educational examination, admissions and degree-certification systems;
medical appointment and public health service systems;
public procurement, tendering, judicial and election-related systems;
systems with explicit protections for minors.

7.2 The specific list of restricted domains is maintained in the developer documentation or the console. We may update it at any time, and we may verify and refuse the relevant requests by technical means.

7.3 For task types that return a verification result, you must submit the target site identifier truthfully as the documentation requires, so that restricted-target checks and after-the-fact tracing can be carried out. If you refuse to submit it or submit a false one, we may refuse service or restrict your account.

8. Customer due diligence

8.1 To identify high-risk use, we may ask you to cooperate with reasonable due diligence at account opening, top-up, limit increases, enterprise onboarding or when anomalies appear, including verifying the identity of the account controller or corporate entity, describing your use case and expected call volume, providing business authorisation or compliance statements, and explaining the source of payment or unusual transactions.

8.2 You must provide truthful information within a reasonable period and cooperate with our enquiries about suspicious activity, without concealing, destroying or fabricating records. If you refuse to cooperate, provide false materials, or we have reasonable grounds to consider the risk unacceptable, we may refuse to open the account, restrict limits, or suspend or terminate the Service, without liability for compensation. We may also, based on our risk model, apply stricter review or limits to particular industries, regions, payment methods or calling patterns.

9. Monitoring, enforcement and abuse reports

9.1 To keep the platform secure and compliant, we may record, analyse and correlate the following: account and API key, call time, task type and result, duration and billing; calling IP, User-Agent, request rate and concurrency characteristics; the target site identifiers you submit; risk-control hits, tickets and report materials. The detailed processing rules are in the Privacy Policy. Monitoring is not a compliance endorsement of your business, and we do not undertake to detect every violation.

9.2 Where a violation occurs or is reasonably suspected, we may, without prior notice, rate-limit or circuit-break particular task types or target domains, freeze API keys, hold refund requests until the investigation completes, suspend or permanently close the account, deduct credits obtained through the violation, and disclose the relevant logs to the competent authorities, rights holders or anti-fraud partners as the law permits. We may apply the same restrictions to payment accounts, API keys, device fingerprints or controllers reasonably linked to the violating account, to prevent ban evasion.

9.3 We are not liable for service interruption, unusable balance or business loss resulting from compliance enforcement, except where the law mandates otherwise. Such enforcement does not affect the statutory refund rights you have under Section 11.

9.4 We are willing, as far as the law allows, to cooperate with law enforcement agencies, regulators, cybersecurity organisations and injured rights holders. On receiving a legally effective request for assistance, or where we have reasonable grounds to believe there are indications of a serious crime, we may provide account information, transaction records and call logs by the statutory procedure, help to stop an ongoing harm, and preserve or hand over electronic evidence.

9.5 Abuse reports: website operators, security vendors, researchers and the public may report abuse through the official Discord community channel. Please include, as far as you can, the time and time zone, the target site or interface, a description of the conduct and evidence, your relationship to the incident and your contact details. We will acknowledge a valid report within 3 working days and give an initial outcome within 10 working days; where verification shows the complaint is likely to be well founded, we will stop serving the account involved. Report materials are handled on a minimum-necessary basis and the identity of good-faith reporters is kept confidential, except where the law requires disclosure. We reserve the right to pursue liability for malicious false reports or fabricated evidence.

10. Billing, top-ups and credits

10.1 The Service is prepaid and billed per successful task. There is no setup fee, no compulsory monthly charge and no minimum spend, unless an enterprise contract provides otherwise.

10.2 Each task type has its own credit price, as shown in the price list on the website or in the console at the time. We may adjust prices; a change applies to calls not yet made and is not applied retroactively to tasks already successfully charged.

10.3 Failed and timed-out tasks are not charged. Whether a task succeeded is determined by our system records. If you believe a charge is wrong, raise it through a console ticket or our official email within 30 days of the charge, with the request id, the time window and the original request details; we will reply within 15 working days of receiving complete information. Tasks not disputed in time are treated as confirmed.

10.4 Paid balance from top-ups remains valid indefinitely and is not cleared on expiry, except in the cases set out in Sections 11.4 and 13.3, or where the account is dealt with under the law or the platform ceases operation. The validity and conditions of promotional bonus credits are governed by the rules of the promotion. An account with no login of any kind for 24 consecutive months and a zero balance may be closed after advance notice.

10.5 Top-up bonuses, package discounts, referral rewards and similar promotional benefits are granted under the rules of the promotion at the time and are not a permanent commitment on future prices; the detailed rules are those published separately for each promotion.

10.6 The payment channels, currencies, statements and invoicing available are those actually enabled in the console. You warrant that you are entitled to use the payment instrument, and you bear responsibility for chargebacks, stolen-card use or improper payments. Where a chargeback, reversal or payment dispute arises, we may freeze the related account and API keys for the duration of the dispute, to prevent repeated loss, until the facts are established. Where fraud or a malicious chargeback is confirmed, we may permanently close the account and reserve the right of recourse.

11. Refunds

11.1 The Service is a digital capability consumed on the spot. Once a top-up has been credited, the paid balance is in principle non-refundable.

11.2 The following cases may be submitted for verification, after which credits may be returned, allowances made up or the payment refunded through the original channel: the same order charged twice; a clear wrong charge caused by a fault in our systems for which you received no corresponding successful task; a voluntary request to close your account with unspent paid balance remaining; and any other case where applicable law mandates a refund.

11.3 The following are outside the scope of refunds: your lacking the technical ability to integrate or use the Service; incompatibility between the Service and third-party scripts, plugins, proxies or browser environments of your choosing; a particular task becoming impossible because a third-party page or verification interaction changed, given that failed tasks are not charged anyway; restriction or closure of your account for breach of these Terms, with serious violations governed by Section 13.3; promotional bonus credits and discount portions; and charges for successful tasks already consumed.

11.4 If we decide to cease operating the Service permanently, or cannot continue to provide it for reasons such as regulatory requirements or force majeure, we will offer a reasonable arrangement for the unspent paid balance in your account, excluding bonus portions, and make reasonable efforts to give 30 days’ advance notice.

11.5 Refund requests must be made within a reasonable period of the event, and for duplicate charges and system errors no later than 30 days, with the order number and proof of payment. We may ask you to help verify control of the account, and we will reply within 15 working days of receiving complete materials. When you close your account voluntarily, the unspent paid balance may be returned through the original channel after outstanding charges, reasonable handling fees and non-refundable portions under these rules are deducted; bonus credits are not refunded.

11.6 We encourage you to contact us before opening a dispute with your payment provider, so that the matter can be resolved faster.

12. Custom capabilities, intellectual property and data

12.1 For recognition tasks not yet covered or of an unusual form, you may submit requirements and samples for us to assess whether we can take them on; the timeline and fees are as confirmed in a separate order between the parties. You warrant that you hold lawful rights to the samples and that they contain nothing unlawful; disputes arising from defects in the rights to the samples are for you to resolve. Ownership of intellectual property in custom models and the scope of delivery are as agreed; without your consent we will not merge samples you have expressly marked for custom use into general models offered to other customers. Fees already incurred for custom services are not refunded unless otherwise agreed.

12.2 Kaptra and its licensors own the website, interfaces, documentation, trademarks, software, models, algorithms and all intellectual property in them relating to the Service. Without written permission you may not copy, modify, rent, distribute or reverse engineer them, or use them beyond the licensed scope, except where mandatory law allows. Without written authorisation you may not use our name, trademarks or pages in a way that suggests sponsorship, partnership or official endorsement.

12.3 You retain your rights in the business data, call parameters and results you lawfully own. To provide the Service, keep it secure and meet our legal obligations, you grant us a worldwide, royalty-free, non-exclusive licence to process that data to the extent necessary. We do not use the task payloads you submit to train general models offered to other customers; quality statistics and security analysis are based on task metadata only. The specific rules for the processing, retention and deletion of personal information and task payloads are those of the Kaptra Privacy Policy.

12.4 We may use, implement or build on feedback and suggestions you submit in the community, in tickets or in reviews without payment, except where mandatory law provides otherwise.

13. Suspension, termination and account closure

13.1 You may stop using the Service at any time and request account closure through a console ticket or our official email. Please export the statements and logs you need before closing.

13.2 We may restrict, suspend or terminate all or part of the Service to you without liability for breach where: you breach these Terms or we have reasonable grounds to believe you are about to; you have not completed necessary verification or have failed it; you are involved in fraud, stolen-card use, malicious chargebacks or disputed payments; action is required by a lawful request from a regulator, law enforcement or a rights holder; we reasonably judge that continuing to serve you would create unacceptable legal, security or reputational risk; or we adjust or discontinue a service as a whole.

13.3 Account handling and balances: where termination results from a serious violation listed in Section 6, the remaining paid and bonus credits in the account may be withheld after set-off against the loss we have suffered. For other ordinary breaches we first give reasonable notice and an opportunity to remedy; if termination follows because the breach is not remedied, the unspent paid balance may be refunded after reasonable costs are deducted, and bonus credits are not refunded. Where we unilaterally cease operation, Section 11.4 applies.

13.4 Provisions of these Terms that by their nature should survive, including intellectual property, confidentiality, disclaimers, limitation of liability, indemnity and governing law, remain in force after termination.

14. Disclaimers, limitation of liability and indemnity

14.1 The Service is provided on an “as is” and “as available” basis. To the fullest extent permitted by applicable law we make no express or implied warranties, including of merchantability, fitness for a particular purpose, non-infringement, continuous and uninterrupted operation, freedom from error or the meeting of all your business metrics. We are not liable for loss caused by network failures, changes to third-party pages or interfaces, force majeure, your parameter errors, key leaks or your breach of these Terms. Documentation, sample code and community discussion are for reference only and are not professional legal, compliance or investment advice.

14.2 To the fullest extent permitted by applicable law, neither we nor our officers, employees or agents are liable for any indirect loss, loss of profit, loss of goodwill, loss of data, cost of procuring substitute services or punitive damages, even if advised of the possibility.

14.3 Our total liability to you shall not exceed the fees you actually paid us in the three months before the event giving rise to the claim; if nothing was paid in that period, the cap is the fees you paid for the tasks in dispute.

14.4 This Section does not exclude or limit liability that cannot be excluded under applicable law, including liability for our wilful misconduct or gross negligence, for death or personal injury caused by us, and for fraud or fraudulent misrepresentation. Where a jurisdiction does not allow implied warranties to be limited or particular liabilities to be excluded, this Section adjusts automatically to the minimum extent the law permits, and the remaining provisions stay in force. Liability arising from your unlawful use of the Service, infringement of third-party rights or breach of these Terms is not covered by the parts of the limitations above that would favour you.

14.5 If your breach of the law or these Terms, the data or samples you submit being infringing or unlawful, your account or keys being used to harm others, or disputes triggered by your automated conduct on third-party sites lead to a claim, investigation or penalty against us by a third party, you shall compensate us for the reasonable losses, fines, settlement sums and legal fees that result and hold us harmless.

15. Third-party services, confidentiality and force majeure

15.1 The Service may contain links to or integrations with third-party websites, payment providers, cloud services or community tools. Those services are the responsibility of their operators and subject to their own terms. Your access to or operations on third-party target sites are a matter between you and that third party; any claim, ban, penalty or loss from a third party is for you to deal with.

15.2 Each party shall keep confidential the non-public technical, commercial, account and security information learned in the course of the relationship, and use it only to the extent necessary to perform these Terms. Information that is public other than through the receiving party’s breach, that the receiving party lawfully developed independently or obtained from a third party under no duty of confidence, or that the law or a competent authority requires to be disclosed, is not confidential information. This clause survives termination of these Terms.

15.3 Neither party is liable for delay or failure to perform caused by events beyond its reasonable control, including natural disasters, war, riots, government action, changes in law or regulation, regional infrastructure failure, large-scale cyber attacks, epidemics, and outages of major cloud providers or payment channels. Where a change in law or government action prevents us from continuing to provide the Service, the unspent paid balance is handled under Section 11.4.

16. Changes to these Terms

We may revise these Terms. The revised version will be published on the website with an updated effective date. For changes that materially and adversely affect your rights or obligations, we will give reasonable advance notice before they take effect, normally no less than 30 days, by website announcement, console notice or email, and we may ask you to confirm again in the console. The specific list of restricted domains under Section 7 is a security operating measure that we may update at any time with immediate effect. If you do not accept the updated Terms, stop using the Service and request account closure before they take effect; continued use after the effective date constitutes acceptance.

17. General

17.1 Entire agreement. These Terms, together with the Privacy Policy, the price list and promotion rules in force at the time and any written documents separately signed by the parties, form the entire agreement and supersede all prior oral or written communication about the Service. Where a formal enterprise contract conflicts with these Terms, the formal contract prevails.

17.2 Severability and waiver. If any provision is held invalid or unenforceable, the remaining provisions are unaffected. Our failure or delay in exercising a right is not a waiver of it.

17.3 Assignment. You may not assign your rights or obligations under these Terms without our written consent. We may assign to a successor in a reorganisation, merger or business transfer and will inform you by reasonable means; if you do not accept the successor, you may request account closure within a reasonable period after the notice, and the unspent paid balance is handled under Section 11.5.

17.4 Relationship and notices. The parties are independent contracting parties; these Terms create no partnership, joint venture, agency or employment relationship. Notices we send to your registered email address or as console messages are deemed delivered when sent; notices you send to us must go through the channels listed in Section 19 and are deemed delivered when we actually receive them.

17.5 Compliance and sanctions. You warrant that neither you, your affiliates nor your end users are on any applicable export-control or economic-sanctions list, and that you will not use the Service in or for a restricted country or region. If you breach this clause we may suspend or terminate the Service immediately.

18. Governing law and disputes

18.1 The formation, validity, interpretation and dispute resolution of these Terms are governed by the law of Kaptra’s place of registration, excluding its conflict-of-laws rules and subject to any mandatory consumer-protection rules that apply.

18.2 Disputes arising from these Terms shall first be negotiated in good faith through the official channels; failing that, they shall be submitted to the competent court of Kaptra’s place of registration, unless applicable law requires or the parties separately agree in writing to arbitration. To prevent irreparable harm we may apply to any competent authority for an injunction or other interim relief.
