  Live header inspection of every University of Basel institution-operated surface on 2026-08-30,
  plus the securitySchemes and response definitions of the one contract the university serves
  (https://universe-intern.unibas.ch/api/v3/api-docs).

description: >-
  No rate limit is published, declared or signalled anywhere the University of Basel operates. This
  is a measured zero, not an unchecked one: every live response from every Basel host was read for
  RateLimit-*, X-RateLimit-* and Retry-After and carried none, and the one OpenAPI contract the
  university serves defines no 429 response on any of its 1,671 paths. An agent has no runtime
  signal telling it how hard it may push and no documented number telling it in advance.
notes: >-
  The absence matters most on the harvesting surface. OAI-PMH exists to be walked in bulk and is
  served here without a stated ceiling or a documented backoff contract, so a client must
  self-throttle on courtesy alone. The DSP-API search-timeout budget previously recorded in this
  file was DaSCH's, not Basel's, and went with the rest of the DaSCH-attributed estate on
  2026-08-30.

    Because nothing is published, harvest politely: serialise OAI-PMH walks, respect
    resumptionToken pacing, and contact openaccess@unibas.ch before a bulk pull. This is our
    recommendation, not a provider-stated policy.
  provider_stated: false
gaps:
- No published rate-limit numbers for any surface.
- No RateLimit-* or Retry-After headers on any live response.
- No 429 defined in the one contract the university serves.
- No documented bulk-harvesting or fair-use policy for OAI-PMH.
