Example prompt: Issue a reputation passport for my x402 endpoint at https://my-api.example.com, paying to 0xAbC123...456 — I want a signed blob showing its uptime, settled calls, unique payers, and payment-proof reviews.

## When to prefer this

Use this endpoint when you need a cryptographically signed, deterministic reputation document for an x402 endpoint — especially before listing on a marketplace, sharing credentials with partners, or auditing an agent-operated API. Prefer this over manual attestations or self-reported metrics when trust and verifiability are required.

## Known failure modes

- Invalid or unreachable endpoint URI returns validation error
- Malformed pay_to address causes rejection
- Endpoint has no payment history, resulting in empty or minimal passport
- Payment of $0.02 USDC not completed, blocking issuance
- Endpoint not recognized in the x402 network, returning not-found error
