How this service works
One paid call on nl-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://nl-cm-kg.ai/x402/receipt/{nonce}. Doctrine: https://agentic-x402.ai/.
Output
Returns a public-record data payload (e.g. a market node's list_nodes entry, a product record, or an estate-scale block), accompanied by an EdDSA-signed receipt and a nonce. The receipt is permanently resolvable at https://nl-cm-kg.ai/x402/receipt/{nonce}, providing a tamper-evident audit trail.
Example use cases
Audit a market node record
“Pull the signed public record for that market node and give me the permanent receipt URL so I can verify it hasn't been tampered with.”
Verify a product listing entry
“Get me the cryptographically signed public record for this product on nl-cm-kg.ai — I need the EdDSA receipt to confirm the data is authentic.”
Retrieve estate-scale block data
“Fetch the signed estate-scale block record from nl-cm-kg.ai and return both the data and the receipt nonce so I can resolve it permanently later.”

Endpoint
GEThttps://nl-cm-kg.ai/api?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically signed, permanently resolvable public-record snapshot from the nl-cm-kg.ai data surface — specifically for market nodes, product records, or estate-scale blocks — and require an EdDSA receipt for auditability or downstream verification. Prefer it over generic data APIs when tamper-evidence and a permanent receipt URL are required.
