How this service works
One paid call on cm-kg.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-kg.io/x402/receipt/{nonce}. Doctrine: https://agentic-x402.ai/.
Output
Returns a public-record payload (market node list_nodes line, product record of record, or estate scale block) accompanied by an EdDSA-signed receipt. The receipt includes a nonce and is permanently resolvable at https://cm-kg.io/x402/receipt/{nonce}.
Example use cases
Verify a market node's public record
“Fetch me the signed public-record entry for the cm-kg.io market node and give me the receipt URL so I can verify it's authentic later.”
Retrieve product record of record
“Get the officially attested record of record for the product listed on cm-kg.io — I need the EdDSA-signed receipt with its permanent nonce link.”
Audit estate scale block for allooloo.io
“Look up the estate scale block for allooloo.io on cm-kg.io and return the signed receipt so I can confirm the public record on the agentic-x402 network.”
Technical details
Endpoint
GEThttps://cm-kg.io/api?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cryptographically attested, permanently resolvable public-record entry from the cm-kg.io knowledge graph — specifically for market nodes, product records, or estate scale blocks on the agentic-x402 doctrine network. Prefer it over generic REST lookups when you require an EdDSA-signed receipt with a durable nonce URL for auditability or downstream verification.
Side effects
- Payment not received — endpoint requires $0.01 USDC via x402 protocol before record is served
- Invalid or unsupported HTTP method — only GET, HEAD, DELETE are accepted
- Record not found — requested node, product, or estate identifier does not exist on cm-kg.io
- Nonce resolution failure — receipt URL may be temporarily unavailable
- Malformed input object — missing required 'type' or 'method' fields returns a schema validation error
