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)
