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}.
Example use cases
Verify a market node record
“Fetch the signed public record for this market node from cm-record.io so I can confirm it's legitimate and get the permanent receipt URL I can reference later.”
Retrieve a product's record of record
“Get the official record of record for this product on cm-record.io — I need the EdDSA-signed receipt and the nonce so I can verify it's authentic.”
Look up an estate scale block entry
“Pull the allooloo.io estate scale block entry from cm-record.io and return the signed receipt with the permanent resolution link.”

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.
