Kings College London Rate Limits

King's College London publishes no rate-limit table on any public surface. Re-checked 2026-08-19: the one institution-operated API, the e-Research AI Hub at ai.create.kcl.ac.uk/api/v1, is metered — new accounts get an allocation of free tokens and sustained use is billed against a project budget — but the limits, the quota units and the 429 shape are all documented behind Microsoft Entra ID sign-in at ai.create.kcl.ac.uk/docs and could not be read. The 401 responses carry no RateLimit or Retry-After headers. The Pure OAI-PMH endpoint at kclpure.kcl.ac.uk/ws/oai answers unauthenticated and publishes no stated limit; harvest politely and honor Retry-After. No 429 was observed on any King's host.
