agente-jefe x402 Protocol & Discovery Metadata Diagnostic
x402
agente-jefe x402 Protocol & Discovery Metadata Diagnostic is a paid API for AI agents from agente.revenuerecoveryai.app, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Validates an x402 payment-gated endpoint without paying — checks protocol correctness (version, CAIP-2 network, currency/network coherence, destination, amount, time window, schema) and Bazaar discovery metadata validity (declared method, schemas, real example, GET-probe compatibility), returning a scored JSON report with prioritized findings and fix guidance.

How this service works
Why an x402 endpoint fails to charge or appear in the Bazaar: verifies the 402 (version, CAIP-2 network, currency, payTo, amount, window) and the discovery listing without paying. Score, findings with fixes, signed receipt. / Por qué un endpoint x402 no cobra o no aparece en el Bazaar: verifica el 402 (versión, red CAIP-2, moneda, destino, importe, ventana) y la ficha de discovery sin pagar. Puntuación, hallazgos con arreglo y recibo firmado.
Output
A JSON object containing a numeric compliance score (0–1 or 0–100), a prioritized list of findings covering x402 protocol issues (version, CAIP-2 network, currency/network coherence, destination address, payment amount, time window, schema shape) and Bazaar discovery metadata issues (declared HTTP method, input/output schemas, example correctness, GET-probe compatibility), suggested fixes for each finding, and optionally a signed diagnostic receipt. The response is fully deterministic — no LLM inference involved.
Example use cases
Pre-launch x402 compliance check
“Before I list my new API on the Bazaar, run a complete diagnostic on https://api.myservice.com/v1/premium (GET method) to check whether my x402 payment headers are spec-compliant and my discovery metadata is valid.”
Debugging 402 network mismatch
“My x402 endpoint at https://payments.myapp.io/resource (GET) keeps getting rejected by agents — can you do a quick diagnostic to see if the CAIP-2 network and USDC currency declarations are coherent?”
Verifying GET probe compatibility
“I want to make sure my Bazaar-listed endpoint https://api.example.com/gated (HEAD method) passes GET-probe crawler checks — run a full x402 and metadata diagnostic and show me the prioritized list of issues to fix.”
Technical details
Endpoint
GEThttps://agente.revenuerecoveryai.app/v1/x402/diagnoseWhen to prefer
Choose this endpoint when you need a deterministic, zero-cost (no actual payment sent) compliance check of an x402-gated API — specifically to validate both the low-level payment protocol (CAIP-2, currency, amount, destination, time window) and the high-level Bazaar discovery metadata in a single call. Prefer it over manual inspection or generic HTTP debuggers when you need a scored, actionable report with prioritized fixes. Ideal before listing an endpoint on the Bazaar or troubleshooting agent discovery failures.
Side effects
- Target URL is unreachable or returns a non-402 status — diagnostic cannot proceed
- Invalid or missing 'url' query parameter — returns 400 validation error
- Target endpoint uses an unsupported HTTP method (POST/PUT/PATCH) — method not diagnosable
- Network timeout reaching the target endpoint — partial results or timeout error
- Malformed x402 response from target makes schema parsing fail — returns parsing error with details
