CedarProof HTTP Response Diagnostics
x402
CedarProof HTTP Response Diagnostics is a paid API for AI agents from cedarproof-diagnostics.cedarproof-lab.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-16).
Classifies an HTTP/JSON response as success, failure, partial, or unknown using fixed deterministic rules based on HTTP status and response body signals.

How this service works
Fixed-rule HTTP/JSON response classification: success, failure, partial or unknown. Public non-sensitive snippets only. No root-cause analysis, repair, AI inference or business-success guarantee. Unknown is a delivered paid result.
Output
Returns a JSON object containing a normalized request_id, the engine version string, a verdict enum (success, failure, partial, or unknown), and an array of one or more reason_codes from a fixed vocabulary (e.g. HTTP_ERROR_STATUS, JSON_RPC_ERROR, GRAPHQL_DATA_WITH_ERRORS, EXPLICIT_TRUE_FLAG). No raw snippet text or upstream exception messages are returned. An 'unknown' verdict is a valid paid result when no recognized signal is found.
Example use cases
Etherscan API failure detection
“I got a 200 back from Etherscan but my app thinks something went wrong — can you run a diagnosis on this response body '{"status":"0","message":"NOTOK","result":""}' with HTTP status 200 using the etherscan profile and request ID f47ac10b-58cc-4372-a567-0e02b2c3d479?”
JSON-RPC error envelope detection
“Check whether this JSON-RPC response body '{"jsonrpc":"2.0","error":{"code":-32600,"message":"Invalid Request"},"id":1}' with HTTP status 200 is actually a failure — use the generic profile and request ID 550e8400-e29b-41d4-a716-446655440000.”
GraphQL partial response classification
“This GraphQL call came back with HTTP 200 and body '{"data":{"user":null},"errors":[{"message":"Not authorized"}]}' — can you diagnose whether that's a success, failure, or partial result? Use generic profile and request ID 6ba7b810-9dad-41d1-80b4-00c04fd430c8.”
Technical details
Endpoint
POSThttps://cedarproof-diagnostics.cedarproof-lab.workers.dev/v1/diagnose?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, rule-based classification of HTTP/JSON responses for automated pipelines — especially when working with Etherscan, JSON-RPC, or GraphQL APIs where a 200 status does not guarantee application-level success. Prefer it over ad-hoc LLM-based response parsing when auditability, fixed cost, and reproducible reason codes matter. Not suitable when root-cause analysis, repair suggestions, or AI inference about business-level success are needed.
Side effects
- Outer input validation failure (missing required fields, non-integer http_status like 200.0) returns a 4xx without charging
- Body snippet exceeding 16384 bytes is rejected as invalid input
- Malformed, empty, or over-depth JSON inside the body field may produce a paid 'unknown' verdict rather than an error
- Reusing a request_id for a new purchase may cause recovery behavior rather than a fresh classification
- HTTP 4xx/5xx statuses are classified from status code alone without parsing the body snippet
- Non-UUID or incorrectly formatted request_id values are rejected
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| bodyrequired | string | Public, non-sensitive response snippet; at most 16384 UTF-8 bytes after JSON string decoding. This is a byte limit, not a character count. Supply the response text as a JSON string, not an object. Empty, malformed, duplicate-key, nonfinite or over-depth JSON inside this field can produce a paid unknown result; it is not rejected as invalid outer input. Do not send credentials, secrets or personal data. HTTP 4xx/5xx is classified from status without examining this snippet. |
| profilerequired | string | Choose from trusted knowledge of the response source. generic checks narrowly recognized top-level boolean/status, JSON-RPC and GraphQL signals. etherscan additionally recognizes string status="0", message="NOTOK" and a nonempty string result. The payload does not authenticate its provider. |
| request_idrequired | string | Generate a fresh UUIDv4 for each intended purchase. This fixed synthetic UUID is for unsigned examples/probes only; do not reuse it for a real purchase. The server normalizes hex to lowercase. Recovery reuses the original ID and identical input/proof. |
| http_statusrequired | integer | Observed HTTP status. Use a JSON integer token: 200 is accepted, while 200.0 and 2e2 are rejected. OpenAPI integer alone does not express this lexical restriction. |
Output
Schema · Response
| Field | Type | Description |
|---|---|---|
| enginerequired | string | |
| verdictrequired | string | success means a recognized success signal; failure means a recognized HTTP/application failure; partial means a GraphQL-shaped object has data plus errors without another explicit failure signal; unknown means no supported conclusion. These are fixed rules, not root-cause analysis or proof of business success. unknown is a delivered result at the same price. |
| request_idrequired | string | The submitted UUID normalized to lowercase. |
| reason_codesrequired | array | Fixed code vocabulary only. No snippet text or upstream exception text is returned. |
