How this service works
Pay-per-result APIs for agents. No signup. Exact price. Verifiable delivery. USDC on Base + Solana via x402.
Output
Returns a JSON object with the matched boolean result, the input host and domain, a pass/fail status, and cryptographic evidence including SHA-256 of the inputs and a confirmation that no data was retained or sent to external services.
Example use cases
Validate cookie scope before deployment
“Before I deploy my new auth cookie, can you verify that the cookie domain 'myapp.io' will correctly match requests from 'login.myapp.io'?”
Debug cookie not being sent
“My cookies aren't being sent on requests from 'payments.internal.acme.com' — can you check whether the cookie domain '.acme.com' actually covers that host?”
Automated cookie config testing
“I'm setting cookies with domain 'shop.example.com' for requests from 'cdn.shop.example.com' — does that match according to browser cookie rules?”
Technical details
Endpoint
POSThttps://commerce.delx.ai/api/v1/x402/cookie-domain-match?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, trustless, pay-per-call verification of cookie domain matching logic without setting up your own implementation. Ideal for agents automating web reliability checks, debugging cookie scoping issues, or validating cookie configurations before deployment. Prefer it over home-grown logic when auditability and verifiable evidence (input hash, no-retention proof) matter.
Side effects
- Invalid or missing request_host or cookie_domain fields returns an error
- Malformed hostname formats may result in failed validation or unexpected match results
- Network timeout if the service is temporarily unavailable
