  description: Gradescope's primary supported integration surface. Implements the 1EdTech LTI 1.3 / LTI Advantage standard,
    including Names and Role Provisioning Services (NRPS) for roster sync, Assignment and Grade Services (AGS) for gradebook
    column creation and grade passback, and Deep Linking for creating Gradescope assignments from within an LMS. Endpoints
    are negotiated per LMS tool deployment rather than exposed as a fixed first-party REST API.

  description: Assignment configuration and the autograder framework for code assignments. The documented programmatic contract
    is a Docker-based autograder that reads student submissions and emits a results.json file (via the gradescope-utils Python
    package); there is no generally available public REST endpoint for creating or listing assignments. Assignment creation
    from an LMS is supported via LTI Deep Linking.
