## How to call it through Zero

```sh

Example prompt: Can you run a Verification Bureau audit on my x402 service at https://my-api.example.com/v1 and tell me whether it passes the compliance standard?

## When to prefer this

Use this endpoint when you need a cryptographically attested, standards-based compliance audit of an x402 service URL — particularly when you need Ed25519-signed proof of conformance for governance, trust verification, or CI/CD gating purposes. Prefer this over manual inspection or generic HTTP checkers when the Bureau standard compliance verdict is required.

## Known failure modes

- Non-HTTPS or malformed URL returns a validation error
- Target URL is unreachable or times out, resulting in an audit failure or network error
- URL does not implement x402 and fails compliance checks, returning ok: false
- Payment of $0.25 USDC on Base mainnet is not settled, resulting in HTTP 402 payment-required response
- Service temporarily unavailable causing 5xx errors

## How this service works

Synthex Forge x402 Receive: 41 paid verification, attestation and governance endpoints (Ed25519 + SHA-256 signed artifacts) plus free verify/public-key/standard sibling routes. Paid routes answer HTTP 402 with an x402 v2 `payment-required` envelope (atomic USDC on Base mainnet, chain ID 8453). Free routes are declared with `security: []` per the x402scan discovery spec.

## Output

Returns a JSON object with an 'ok' boolean indicating whether the submitted URL passes the Verification Bureau audit standard. In practice the full response may include Ed25519-signed attestation artifacts and SHA-256 checksums confirming compliance status.
