source: live HTTP probes of the Landcor API host and web hosts, 2026-07-26
note: >-
  Landcor publishes no /.well-known/ discovery documents on any host. Every probe returned
  404, including on api.landcor.com, which does serve a live OpenAPI 3.1.0 document at
  /openapi.json. The FastAPI service exposes the spec and its Swagger UI / ReDoc renders but
  no discovery layer around them: no security.txt, no OAuth or OIDC metadata (consistent with
  the single HTTPBearer scheme, which is an opaque token with no published issuer), no
  api-catalog and no ai-plugin. This is an honest negative result, not an incomplete probe.
  No llms.txt is published either, so llms/landcor-llms.txt is GENERATED from this catalog
  rather than harvested.
