How this service works
One paid call on cm-kg.org 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-kg.org/x402/receipt/{nonce}. Doctrine: https://agentic-x402.ai/.
Output
A public-record payload for the requested surface (market node list_nodes line, product record of record, or estate-scale block), accompanied by an EdDSA-signed receipt that is permanently resolvable at https://cm-kg.org/x402/receipt/{nonce}.
Example use cases
Verify a market node record
“Get the signed public record for the market node on cm-kg.org and show me the nonce receipt URL so I can confirm it's authentic.”
Retrieve a product record of record
“Fetch the record of record for the product listed on cm-kg.org and give me the EdDSA-signed receipt with the permanent resolve link.”
Look up an estate-scale block entry
“Pull the estate-scale block entry from cm-kg.org's public record and return the signed receipt so I have a verifiable proof URL.”

Endpoint
GEThttps://cm-kg.org/api?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically signed, permanently resolvable public-record lookup for a specific cm-kg.org surface (market node, product, or estate-scale block) and require an EdDSA receipt for auditability or downstream verification. Prefer it over generic web lookups when verifiable provenance and a permanent nonce receipt URL are required.
Side effects

- Requested surface or node identifier not found returns an empty or 404 response
- Payment of $0.01 USDC not completed returns a 402 Payment Required before data is served
- Nonce receipt URL may not resolve if the network is congested or the service is temporarily unavailable
