generated: '2026-09-20' method: probed source: live probes of /.well-known/ on windowsticker.org summary: >- One real document is served: an RFC 9727 API Catalog (application/linkset+json) at /.well-known/api-catalog, pointing at the OpenAPI, the human docs and the status page. That is a genuine WellKnown hit and the pointer is earned. Nothing else is served: no security.txt (so NO SecurityTxt pointer), no OIDC/OAuth discovery, no ai-plugin.json, and no A2A agent card. This is a keyless public API with no OAuth surface, so the absence of the oauth/openid documents is expected, not a gap. pointer_basis: >- WellKnown pointer emitted on the strength of the 200 application/linkset+json at /.well-known/api-catalog. SecurityTxt NOT emitted — RFC 9116 is unimplemented. false_positive_watch: >- windowsticker.org answers HTTP 404 with a full HTML app-shell (24,965 bytes, ) for every unknown /.well-known/* path. Those are recorded below as 404 misses, not hits. api-catalog is the only path returning a real machine-readable body. hosts: - host: https://windowsticker.org documents: - path: /.well-known/api-catalog status: 200 content_type: application/linkset+json file: window-sticker-vin-api-api-catalog.json - path: /.well-known/security.txt status: 404 - path: /.well-known/openid-configuration status: 404 - path: /.well-known/oauth-authorization-server status: 404 - path: /.well-known/oauth-protected-resource status: 404 - path: /.well-known/ai-plugin.json status: 404 - path: /.well-known/agent-card.json status: 404 - path: /.well-known/agent.json status: 404 checked: '2026-09-20'
