## 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 cm-record-io-public-record-lookup-5f4bc457
```

Example prompt: Pull the official public record for this market node from cm-record.io and give me the EdDSA-signed receipt with the permanent nonce link.

## When to prefer this

Choose this endpoint when you need a cryptographically verifiable, permanently resolvable public record for a cm-record.io surface — such as a market node, product, or estate block — and require an EdDSA-signed receipt as proof. It is purpose-built for agentic x402 workflows where tamper-evidence and permanent nonce-based resolution matter.

## Known failure modes

- Invalid or missing 'type' field (must be 'http') returns a validation error
- Unsupported HTTP method (must be GET, HEAD, or DELETE) returns a 400 error
- Payment not completed or insufficient USDC balance blocks the call
- Unknown or non-existent surface/record identifier returns a not-found error
- Network timeout or service unavailability returns a 5xx error

## How this service works

One paid call on cm-record.io for $0.01 USDC: the surface's own statement of record (a market node: its list_nodes line; a product: its record of record; allooloo.io: the estate scale block), public-record only, with an EdDSA-signed receipt that resolves forever at https://cm-record.io/x402/receipt/{nonce}. Doctrine: https://agentic-x402.ai/.

## Output

Returns a public record entry for the requested surface (market node list_nodes line, product record, or estate scale block), accompanied by an EdDSA-signed receipt and a nonce. The receipt is permanently resolvable at https://cm-record.io/x402/receipt/{nonce}.
