Public API documentation
LobbyStack exposes a small public discovery surface so agents can find documentation, status, OpenAPI metadata, skills, and machine-readable usage preferences without scraping the site.
These public discovery endpoints do not require authentication. OAuth metadata will be published on the app host when protected APIs expose real authorization endpoints.
API catalog
RFC 9727 linkset for public API and discovery resources.
OpenAPI
JSON description of the public discovery endpoints.
Status
Lightweight public health signal for automated clients.
