Usc Rate Limits

University of Southern California publishes no rate-limit documentation of any kind, for any surface. Corrected 2026-08-30: the previous text here cited OAI-PMH, IIIF and library harvesting endpoints as the throttled surfaces, and USC operates none of them - every OAI-PMH path probed on digitallibrary.usc.edu, repository.usc.edu and the Ex Libris Alma gateway for institution code 01USC_INST failed. Clients of the two keyless USC surfaces that do exist (shibboleth.usc.edu metadata, facebase.org ERMrest) should still back off politely and honor Retry-After; no published limit governs either.

Usc Rate Limits is the machine-readable rate-limit profile for University of Southern California on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 1 rate-limit definition, measuring requests-per-minute.

The profile also includes 1 backoff/retry policy defined and response codes documented for throttled.

Tagged areas include Education, Higher Education, University, and Rate Limiting.

none published
No rate limit is published or advertised on any USC-operated surface, and no 429 or RateLimit-* header was observed on any probe. Absence of a documented limit is not a guarantee of an unlimited service.

Policies

Backoff Strategy
Exponential backoff with jitter; honor Retry-After; harvest during off-peak hours.
