Terms of Service

Last updated: 5 November 2026. These Terms apply on every SiteCheck host listed at api.sitecheck-api.workers.dev.

1. Who we are and what you accept

"SiteCheck", "we" and "us" mean the operator of the SiteCheck service and its hosts. Contact: sitechecktools@gmail.com.

By calling any SiteCheck endpoint, directly over HTTP, through the MCP or A2A interfaces, or through an AI agent, script or other software acting for you, you accept these Terms and our Privacy Policy. If you do not accept them, do not use the service.

You are responsible for every call made with your wallet, keys or credentials and for every call made by an agent or program you run, deploy or authorise, as if you had made it yourself. If you accept these Terms for an organisation, you confirm that you may bind it, and "you" includes that organisation.

2. Business use only

SiteCheck is offered to businesses, developers and professionals for use in their trade, business or profession. It is not offered to consumers. By using it you confirm that you act for business purposes and that you are at least 18 years old.

3. Prices and payment

• Each call is paid with the x402 protocol, in the asset and on the network you choose from those offered. The price that binds you is the one stated in the HTTP 402 answer (PAYMENT-REQUIRED) for that call at the time you pay. The price list is for information only.
• Payment settles only when the call succeeds. A call that fails, including an answer with an error status or a 503 from a source, is not charged.
• Payments are made on public blockchains and are final and irreversible once settled. Network fees, wallet services and payment facilitators are provided by third parties, are not our agents, and are outside our control.
• If you are charged for a call that, under the rule above, should not have been charged, write to us within 30 days with the transaction hash. After checking it we will return that amount to the paying address in the same asset. This is your only remedy for a billing error; no other refunds are given.
• You are responsible for any taxes that apply to your payments.

4. Results and sources

Results come from public and third-party sources (registries, websites, APIs, blockchains, data providers) and, for some tools, from AI models. They are passed on as received or summarised automatically, and they can be incomplete, outdated, delayed or wrong. We do not check them and do not warrant their accuracy, completeness or fitness for any purpose.

Results are information only. They are not financial, investment, trading, legal, tax, medical, safety, credit, insurance or other professional advice, and they are not an official record, certificate or compliance determination. Screening tools (sanctions, security, email, identity and similar) are aids; you make and are responsible for every decision based on them and must check important results against the original source.

SiteCheck is not a consumer reporting agency. You must not use results as a factor in decisions about a person's eligibility for credit, insurance, employment, housing or similar purposes under the US Fair Credit Reporting Act or comparable laws.

Content in results that belongs to a source remains that source's. You are responsible for making sure that your use, storage and redistribution of results complies with the law (including copyright, database rights and data protection law) and with the terms of the original source.

5. Acceptable use

• Do not use SiteCheck for anything unlawful, to harass, track, stalk or discriminate against any person, to build profiles of individuals without a lawful basis, or to infringe anyone's rights.
• Do not attack, overload, scan for weaknesses or try to bypass payment, rate limits or other controls, and do not use the service to attack or overload third-party sources.
• Do not use SiteCheck if you are, or act for, a person subject to sanctions, or from a country or region where the service or the payment would be prohibited.
• We may refuse, limit or block calls, wallets, networks or clients at any time to protect the service, its sources or third parties, or to comply with law.

6. Personal data in your calls

When a call contains or asks for information about an identifiable person, you decide why and how that data is processed and you are the controller for it. You confirm that you have a lawful basis for each such call and that you will use the result lawfully. We process the data only to answer the call, as described in the Privacy Policy. Do not send special-category or other sensitive personal data unless the tool requires it and you are allowed to.

7. Availability and changes

SiteCheck has no service level, uptime or support commitment. We may change, suspend or withdraw any tool, price, network, host or feature, and stop the service, at any time and without notice. A change of price takes effect for calls paid after the change.

8. No warranties

To the fullest extent permitted by law, SiteCheck and all results are provided "as is" and "as available", with all faults and without any warranty, condition or representation of any kind, express, implied or statutory, including any implied terms of satisfactory quality, merchantability, fitness for a particular purpose, accuracy, non-infringement, or uninterrupted or error-free operation.

9. Limitation of liability

• We are not liable, in contract, tort (including negligence), breach of statutory duty or otherwise, for any indirect, special or consequential loss, or for any loss of profit, revenue, business, contracts, opportunity, goodwill, data or anticipated savings, whether direct or indirect.
• We are not liable for any loss arising from: your reliance on any result; the actions or decisions of any AI agent or program, whoever runs it; any third-party source, wallet, blockchain, network, payment facilitator, proxy or hosting provider; or any call made with your wallet or credentials.
• Our total aggregate liability for all claims arising out of or in connection with SiteCheck or these Terms is limited to the amounts you paid us for calls in the 12 months before the event that gave rise to the first claim.
• Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or any other liability that cannot be excluded or limited by law.

10. Indemnity

You will defend, indemnify and hold harmless SiteCheck and its operator against all claims, losses, liabilities, damages, fines, costs and expenses (including reasonable legal fees) arising from your use of the service or of results, your calls and the data in them, the conduct of any agent or program acting for you, or your breach of these Terms or of any law or third-party right.

11. Suspension and ending

We may suspend or end your access at any time. You may stop using the service at any time. Sections 3 (final payments and billing errors), 4, 6, 8, 9, 10 and 13 continue to apply after use ends.

12. Changes to these Terms

We may change these Terms by publishing a new version at /terms with a new date. The version published when you make a call applies to that call.

13. Law and courts

These Terms and any dispute or claim (including non-contractual disputes or claims) arising out of or in connection with them or with SiteCheck are governed by the law of England and Wales. The courts of England and Wales have exclusive jurisdiction.

14. General

These Terms and the Privacy Policy are the whole agreement between you and us about SiteCheck. If any provision is found invalid or unenforceable, it is modified to the minimum extent needed to make it enforceable, and the rest stays in effect. Not enforcing a provision is not a waiver. We are not responsible for delay or failure caused by events beyond our reasonable control. You may not transfer your rights under these Terms; we may. No one other than you and us has any right to enforce these Terms, except our operator under section 10. These Terms are written in English, and the English text prevails over any translation.
