CedarProof HTTP/JSON response classification
POST a public, non-sensitive HTTP status and response-body snippet for fixed-rule classification as success, failure, partial or unknown, with machine-readable reason codes. Generic and Etherscan profiles. 0.01 native USDC on Base per delivered result; unknown is also a paid result. No URL fetching, code execution, AI inference, root-cause diagnosis, repair or guarantee of business success. Exactly four JSON fields; use a fresh UUIDv4 for each new intended purchase. Preserve the original ID, identical input and payment proof for recovery; do not create a replacement payment automatically. An unresolved payment can return202. API and limits: https://cedarproof-diagnostics.cedarproof-lab.workers.dev/openapi.json Base USDC paid settlement and delivery have not yet been independently demonstrated for this endpoint.
