How this service works
One paid call on kr-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://kr-cm-kg.ai/x402/receipt/{nonce}. Doctrine: https://agentic-x402.ai/.
Output
A public-record response containing the surface's entry (list_nodes line for market nodes, record of record for products, or estate scale block), accompanied by an EdDSA-signed receipt and a permanent resolution URL at https://kr-cm-kg.ai/x402/receipt/{nonce}.
Example use cases
Verify a market node record
“Look up the public record for the market node on kr-cm-kg.ai and return the signed receipt so I can verify it's authentic.”
Retrieve product record with proof
“Get the official record of record for this product on kr-cm-kg.ai and give me the EdDSA receipt URL I can share as permanent proof.”
Fetch estate scale block entry
“Pull the estate scale block entry from kr-cm-kg.ai and give me the signed receipt with the nonce so I can resolve it later.”
Technical details
Endpoint
GEThttps://kr-cm-kg.ai/api?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a cryptographically signed, permanently resolvable public-record lookup for a kr-cm-kg.ai surface node, product, or estate scale block. It is particularly suited for agentic workflows requiring tamper-proof receipts with EdDSA signatures and permanent receipt URLs. Prefer it over generic record lookups when the auditability and permanent verifiability of the result is important.
Side effects
- Payment not completed — endpoint requires $0.01 USDC via x402 protocol before record is returned
- Invalid or unsupported HTTP method — only GET, HEAD, DELETE are accepted
- Node or surface not found — requested identifier does not correspond to a known record
- Signature verification failure — EdDSA receipt cannot be validated at the nonce URL
- Rate limiting or network error — transient failure requiring retry
