description: >-
  Gradescope does not publish a generally available public REST API, and it
  does not document public rate limits or quotas for one. Programmatic
  integration occurs through LTI 1.3 / LTI Advantage service calls (NRPS, AGS,
  Deep Linking), whose throughput is governed by the connected LMS and the LTI
  standard rather than by a published Gradescope API rate-limit policy, and
  through the autograder framework, where throughput is bounded by container
  grading capacity rather than by HTTP request limits. No specific limit values
  are reconciled in this artifact.
notes: >-
  No public Gradescope API rate limits are documented. LTI service throughput
  is LMS- and standard-dependent; autograder throughput is bounded by grading
  container resources and configured timeouts. Verify any operational limits
  with Gradescope / Turnitin during reconciliation.

responseCodes:
  throttled: not documented
limits:
- name: Public API Rate Limit
  scope: account
  metric: requests
  limit: not documented (no generally available public REST API)
  notes: Gradescope does not publish a public REST API or its rate limits.
- name: LTI Service Calls (NRPS / AGS / Deep Linking)
  scope: deployment
  metric: requests
  limit: governed by LMS and LTI 1.3 standard
  notes: Throughput for roster sync and grade passback is mediated by the connected LMS, not a published Gradescope limit.
- name: Autograder Execution
  scope: assignment
  metric: jobs
  limit: bounded by grading container resources and timeout
  notes: Autograder throughput is constrained by container CPU/memory and configured run timeouts rather than HTTP request limits.
policies:
- name: No Published API Quotas
  description: Gradescope does not document public API quotas because no generally available public REST API is offered.
- name: Backoff Strategy
  description: For LTI integrations, clients should follow the connected LMS guidance and standard exponential backoff with jitter on transient errors.
