# agente-jefe x402 Protocol & Discovery Metadata Diagnostic

> 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.

## Facts

- Endpoint: GET https://agente.revenuerecoveryai.app/v1/x402/diagnose
- Price: $0.01/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/agente-jefe-x402-protocol-discovery-metadata-diagnostic-847a5e45
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Gz4wjZJlioeBEYUJz5Xiw

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability agente-jefe-x402-protocol-discovery-metadata-diagnostic-847a5e45
```

Example prompt: Run a full diagnostic on my x402 endpoint at https://api.myapp.com/v1/data (GET method) and tell me if the 402 payment protocol and Bazaar discovery metadata are correctly configured — include a signed receipt in the results.

## When to prefer this

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.

## Known failure modes

- 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

## 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.
