description: >-
  University of the Witwatersrand publishes no rate-limit table. The two surfaces it operates —
  the WIReDSpace DSpace 9.2 REST API and the WIReDSpace OAI-PMH 2.0 endpoint — returned no
  RateLimit or X-RateLimit headers and no 429 on probing, and neither documents a published
  ceiling. OAI-PMH harvesting is resumption-token paced by protocol. Clients should harvest
  politely, honor Retry-After, and contact the Wits Library open scholarship team
  (openscholarship.library@wits.ac.za) for bulk access.
notes: Confirm per-service limits with each API's documentation; harvest responsibly.
