UMD Libraries Website Tools API

API middleware operated by the University of Maryland Libraries that exposes today's open/closed status, current bookable-space availability, and raw LibCal space records for five UMD library locations. Thirteen GET operations, no API key, OpenAPI 3.1.0 served from the service itself. The upstream contract is framework-generated: its title is the FastAPI default and its server URL is relative, both repaired in the refined copy with the pristine original kept alongside.

  title: UMD Libraries Website Tools API
  summary: Library hours, bookable-space availability and space details for the University of Maryland Libraries.
  description: 'The Website Tools API is API middleware operated by the University of Maryland Libraries. It fronts
    the Libraries'' Springshare LibApps/LibCal tenancy and exposes today''s open/closed status, current bookable-space
    availability, and raw space records for five UMD library locations (McKeldin, STEM, the STEM Makerspace, the
    Michelle Smith Performing Arts Library, and the Art Library). It is the read side of the umd-lib/website-libtools
    service and drives the hours and room-availability widgets on www.lib.umd.edu.


    The service is documented on the UMD Libraries Open Data site at https://opendata.lib.umd.edu/services/library-website-tools/
    and requires no API key. All operations are GET and read-only.


    Interface note: the upstream document is the FastAPI-generated OpenAPI served at https://api.www.lib.umd.edu/api/libtools/openapi.json.
    That document carries the framework default info.title of ''FastAPI'' and a relative server of ''/api/libtools''.
    This refined copy names the service, absolutises the server URL, and adds tags, human descriptions, probed response
    schemas and the observed 404 shape. The pristine harvested document is kept at openapi/_original/. No operation
    or parameter was added or removed.'
