description: >-
  King Saud University publishes no rate-limit policy for any of its surfaces. The
  Open Data distributions at data.ksu.edu.sa are static files served by Drupal; 20
  consecutive anonymous requests on 2026-09-01, including two multi-megabyte JSON
  fetches, all returned HTTP 200 with no throttling headers, no Retry-After and no
  429. The identity plane at iam.ksu.edu.sa publishes no documented limits either.
  Absence of an observed limit is not a guarantee of an unlimited service — treat
  bulk retrieval politely and cache, since these datasets are refreshed annually.
notes: >-
  Corrected 2026-09-01. The previous version of this file referenced OAI-PMH and
  IIIF harvesting endpoints; King Saud University operates neither. Its only
  former OAI-PMH endpoint, at repository.ksu.edu.sa, is NXDOMAIN.

  notes: >-
    No published limit and none observed. Probed 2026-09-01 across 20 files with
    no throttling response.
- name: Identity plane
  scope: client
  metric: requests
  limit: not published
  notes: >-
    iam.ksu.edu.sa publishes no rate-limit documentation. Endpoints are not
    self-service, so limits would be set per issued client.
policies:
- name: Backoff Strategy
  description: >-
    No provider policy exists. Recommended client practice only: exponential
    backoff with jitter, honour any Retry-After, and cache annually-refreshed
    datasets rather than re-fetching.
