Tool detail
SCVD General Store
Returns previously recorded, signed observations about a named host's x402 door - check rounds, verdicts, coverage and gaps - without making a live request to it.
Categories: API testing, Agent trust safety
Use when
- look up recorded verification history for an x402 host before paying it
- check coverage gaps in an observatory's record of a host
Not for
- not a live check - returns only what was already recorded, possibly stale
- not a guarantee or ranking - an unmet host returns not_observed
Inputs
GET query params: host (string hostname, required); optional agent_name, came_from, client, model, operator, operator_kind, prior_cert_id, purpose (metadata, cosmetic on the receipt)
