How this service works
The machine economy's general store. A human keeper, an AI counter, real goods and honest books. USDC on Base over x402. Pipe-testers welcome.
Output
A signed and dated attestation document (certificate) created by the keeper based on firsthand real-world observation, along with a patron badge. The name provided appears on both the certificate and badge. If a callback URL is supplied, the completed deliverable is POSTed to that URL when the human-queue order finishes.
Example use cases
Agent milestone human certification
“I want a real human to officially witness and sign off on a milestone my AI agent just completed — get me a dated attestation from scvd.store with the name 'AgentBot-7' on it.”
Personal quirky proof-of-existence record
“Can you buy me one of those human witness certificates from scvd.store? Put my name 'Jordan' on it and have the result posted to https://jordan.dev/hooks/witness when it's done.”
Novel novelty gift attestation
“I want to give someone a unique gift — a genuine signed and dated attestation from a real human witness at scvd.store with their name 'Sam' on the certificate.”
Technical details
Endpoint
GEThttps://scvd.store/api/buy/human_witnessWhen to prefer
Choose this endpoint when you need a genuine, firsthand human witness attestation rather than an automated or AI-generated certificate. It is uniquely suited for novelty, creative, or sentimental use cases where the human origin and signed/dated nature of the document matters. Prefer it over AI-generated certificates when the 'real human' provenance is the point of the deliverable.
Side effects
- No callback URL provided and order is in human queue — result may not be immediately available
- Invalid or unreachable callback URL — delivery of result fails silently
- agent_name exceeds 80 characters — may be truncated or rejected
- Payment not completed via x402 — endpoint returns 402 Payment Required
- Human keeper unavailable or queue delay — response takes longer than expected
