How this service works
One paid call on fr-cm-kg.ai 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://fr-cm-kg.ai/x402/receipt/{nonce}. Doctrine: https://agentic-x402.ai/.
Output
Returns the public record of the queried surface (market node list_nodes entry, product record, or estate-scale block) along with an EdDSA-signed receipt containing a nonce that permanently resolves at https://fr-cm-kg.ai/x402/receipt/{nonce}.
Example use cases
Verify a market node record
“Pull the public list_nodes record for this market node on fr-cm-kg.ai and give me the signed receipt so I can verify it permanently.”
Retrieve a product record with proof
“Fetch the product record of record from fr-cm-kg.ai and return the EdDSA-signed receipt URL so I have permanent cryptographic proof.”
Look up estate scale block
“Get me the estate scale block record from allooloo.io via fr-cm-kg.ai, including the signed receipt nonce for permanent resolution.”
