description: >-
  University College Dublin publishes no rate-limit table at all, because it runs no API
  programme. The one keyless institution-operated interface — the OAI-PMH 2.0 endpoint at
  https://researchrepository.ucd.ie/server/oai/request — advertises no quota, no
  X-RateLimit headers and no Retry-After; it does apply OAI-PMH flow control, returning a
  resumptionToken with completeListSize 17167 and a 100-record page on ListIdentifiers
  (observed 2026-08-30), which is pagination rather than a rate limit. Harvest politely and
  contact research.repository@ucd.ie for bulk access. The IIIF endpoints cited in the
  2026-06-03 version of this file no longer exist; the UCD Digital Library platform was
  decommissioned and digital.ucd.ie now serves static data files.
notes: Confirm per-service limits with each API's documentation; harvest responsibly.
