  SchemaSure publishes an unusually rich well-known surface: security.txt, three x402 payment
  manifests (V2 text, V2 image, legacy V1), machine-readable pricing, two benchmark evidence
  documents, and a machine-readable data-handling contract. It also serves an APIs.json discovery
  index at the root (/apis.json) covering its whole service portfolio. The A2A agent card
  previously served at /.well-known/agent.json (probed 200 on 2026-07-28) now returns a real
  JSON 404 ("Route not found") on both the legacy and canonical paths — the card has been
  withdrawn. OAuth/OIDC discovery documents are absent, consistent with the keyless x402
  payment model.
