x402 Endpoint Health & Payment Terms Checker
x402
x402 Endpoint Health & Payment Terms Checker is a paid API for AI agents from agoreum.xyz, paid per call via x402, $0.5/call, status unknown (last checked 2026-10-16).
Probes an x402-enabled HTTPS endpoint for reachability, TLS validity, latency, correct 402 response, and valid parseable payment terms.

How this service works
Probes an x402 endpoint: reachability, TLS, latency, the 402 response and whether its payment terms parse and make sense.
Output
Returns a structured diagnostic report covering: whether the endpoint is reachable, TLS certificate validity, measured latency, whether the endpoint returns an HTTP 402 status, and whether the payment terms in the 402 response are present and parse into valid, coherent payment instructions.
Example use cases
Pre-launch x402 API validation
“Before I go live, check https://api.myproduct.com/generate and confirm it's reachable, TLS is solid, it returns a real 402, and the payment terms are structured correctly so agents can actually pay.”
Debugging broken agent payments
“My agents keep failing to pay for https://partner.example.com/api/v1/infer — can you probe that endpoint and tell me if the 402 response and payment terms are valid, or if TLS or reachability is the issue?”
Third-party x402 service due diligence
“I'm thinking of integrating https://data.thirdparty.io/lookup into my workflow — can you check whether it's properly set up as an x402 endpoint, what the latency looks like, and whether its payment terms make sense?”
Technical details
Endpoint
POSThttps://agoreum.xyz/api/v1/x402/tools/x402-endpoint-check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to validate that a specific x402-enabled HTTPS URL is correctly configured as a pay-per-call API — covering the full stack from reachability and TLS through to 402 response correctness and payment term semantics. Prefer this over generic HTTP health checkers when the x402 payment protocol compliance is specifically what you need to verify.
Side effects
- Non-HTTPS URLs rejected by schema pattern validation
- Endpoint is unreachable or times out — reachability check fails
- TLS certificate is invalid or expired — TLS check fails
- Endpoint returns 200 or other non-402 status — flagged as misconfigured
- 402 response present but payment terms are malformed or unparseable
- Network errors or DNS failures prevent probe from completing
