How this service works

Premium endpoint verification with full attestation

Output

Returns a verification object containing the health status, reachability result, and full attestation of the probed HTTP endpoint, confirming whether it responded correctly to the given request

Example use cases

Example prompt

“Can you do a full premium probe and attestation check on my POST endpoint at https://api.myservice.com/submit, sending a JSON body like {"test":true}, and give me the complete verification result?”

Technical details

Endpoint

POSThttps://probe.onchainintel.net/api/verify

When to prefer

Choose this endpoint when you need not just a basic health ping but a full attested verification — i.e., cryptographic proof that an HTTP endpoint is live and responding correctly. Prefer it over lightweight ping alternatives when compliance, audit trails, or onchain attestation of endpoint status is required.

Side effects

Target endpoint unreachable or times out — returns error with connection failure details
Invalid or missing required input fields (type, method, bodyType, body) — returns 400-class validation error
Payment of 1 USDC not fulfilled — returns 402 Payment Required
Target endpoint returns unexpected status code — attestation may reflect failure state
Malformed JSON body — returns schema validation error
