How this service works
Spot Check. Name a host and get what this observatory already holds on it, signed: corpus rounds and verdicts as recorded, when we last actually knocked, our coverage of the window since we met it, and the gaps with their reasons. Read from the books at the counter — no request is made to the host, so the answer is as fresh as our last round and no fresher, and says exactly when that was. A host we have never observed returns not_observed, which is an answer about our books,…
Output
A signed JSON report containing: the corpus rounds SCVD has recorded for the host, verdicts as captured at observation time, the exact timestamp of the last live probe, coverage percentage of the observation window, and any identified gaps with their reasons. If the host has never been observed, returns a signed not_observed response indicating the absence is itself a definitive answer about SCVD's books. The response is signed by SCVD, attesting to the authenticity of the stored data.
Example use cases
Due diligence on unfamiliar API host
“Before I send traffic to api.newvendor.io, check what SCVD has on record for it — I want to see their past verdicts, when they last observed it, and any gaps in coverage.”
Confirming freshness of prior observations
“What's the most recent time SCVD actually checked payments.acmecorp.com, and how complete is their coverage window since first contact?”
Flagging never-observed hosts in agent workflow
“My agent is about to trust a payment offer from unknownhost.xyz — has SCVD ever observed that host at all, or would it come back as not_observed?”
Technical details
Endpoint
GEThttps://scvd.store/api/buy/spot_checkWhen to prefer
Choose this endpoint when you need a fast, signed, cached report on a host's observation history without triggering a live probe. It is ideal for due-diligence workflows, trust-checking before agent interactions, or auditing SCVD's historical coverage of a domain. Prefer it over live-check endpoints when you want to know what is already recorded rather than what is true right now, or when you need a cryptographically signed attestation of SCVD's books rather than a fresh measurement.
Side effects
- Host never observed — returns a signed not_observed response (not an error, but an authoritative statement)
- Invalid or malformed hostname input — likely a 400-level validation error
- Response freshness limited to last observation round — callers expecting real-time data will be disappointed
- agent_name exceeding 80 characters may be truncated or rejected
- Payment failure over x402 protocol halts the request before data is returned
