## 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 scriptmasterlabs-citemesh-paid-attestation-cite-attest-settle-0e4499a1 -d '<json body>'
```

Example prompt: Check the source at https://example.com/article-123 against the CiteMesh known-source registry, correlate it with match ID 'req-abc-789', and settle the attestation payment so I get a delivery proof back.

## When to prefer this

Choose this endpoint when you need a verifiable, pay-per-call attestation that a specific source URL is recognized in the CiteMesh known-source registry and want cryptographic or documented proof of accepted delivery. It is best suited for x402-compatible agents that need to combine provider verification with a micro-payment settlement in a single call, particularly when an audit trail or citation proof is required downstream.

## Known failure modes

- Source URL not found in the known-source registry — returns an error indicating the URL is unrecognized
- Payment not completed or rejected by x402 protocol — call not settled, no attestation returned
- Invalid or malformed source_url — request rejected with a validation error
- Service unavailable or route misconfigured — no live values returned
- Delivery not accepted — payment may still be attempted but attestation proof not issued

## How this service works

Pay-per-call APIs and a read-only provider check for x402 buyers. Inspect evidence and live terms before a caller-controlled payment; accept delivery with proof.

## Output

After a successful micro-payment and accepted delivery, the endpoint returns a JSON object confirming delivery acceptance, attestation product details ('SML CiteMesh Paid Attestation'), and route-specific live values including proof tokens and terms that were active at settlement time.
