# jurat.dev x402 Conformance Report

> jurat.dev x402 Conformance Report is a paid API for AI agents from jurat.dev, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-15).

Runs a signed x402 pre-flight and conformance check against a target service URL, returning a graded report with ed25519-attested findings

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 jurat-dev-x402-conformance-report-587b2e65
```

Example prompt: Run an x402 conformance check on https://zaref.dev and give me the grade, score, and signed attestation report so I can see how well it meets the spec.

## When to prefer this

Choose this endpoint when you need a cryptographically signed, independently verifiable conformance certificate for an x402-speaking API — especially for pre-launch audits, partner due diligence, or regulatory evidence. Unlike manual inspection or generic API linting tools, this produces an ed25519-attested report with a permanent retrieval URL, making the findings tamper-evident and shareable.

## Known failure modes

- Target URL is unreachable or returns errors — report may have low coverage or fail entirely
- Service has no x402 declarations — coverage will be 0 and grade will be low
- Over 40-endpoint sweep budget — additional endpoints listed as not_checked
- Payment of 0.5 USDC via x402 fails — request is rejected before report is generated
- Malformed or non-HTTP URL provided — request rejected with validation error

## How this service works

Signed conformance report over a whole x402 service. Sweeps every paid endpoint the service declares, GET and POST alike, runs the same checks /v1/preflight runs on each, grades the result, and returns an ed25519-signed report the operator can publish and anyone can verify offline. Coverage is inside the signature, so a partial sweep can never be passed off as a full one. Retrieving any report is free forever.

## Output

A signed JSON object containing: a conformance grade (A–F), numeric score (0–100), coverage ratio, total checks run, per-endpoint findings with pass/fail status, a SHA256 of all findings, the ed25519 signature and public key ID, and a permanent free retrieval URL for the report.
