Washington University In St Louis Rate Limits

Washington University in St. Louis publishes no institution-wide rate-limit policy, and there is no central gateway whose limits would apply across its surfaces. Exactly one WashU-operated API documents a concrete number: CIViC, the McDonnell Genome Institute knowledgebase, states an anonymous ceiling of 3 requests per second measured over a five-minute window, burstable above that rate for short periods and raised by a free API key. Everything else is either behind an internal access request (the MuleSoft Anypoint enterprise APIs, whose limits are not published) or is an OAI-PMH harvesting endpoint with a prose harvesting policy rather than a numeric limit.

Washington University In St Louis Rate Limits is the machine-readable rate-limit profile for Washington University in St. Louis on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 4 rate-limit definitions, measuring requests-per-second, policy, and unknown.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

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

Limits

CIViC GraphQL — anonymous client
requests-per-second
3
Documented by the operator as "rate-limited to 3 requests / second as measured over a 5 minute window", which permits bursting above the rate briefly or sustaining it indefinitely.
CIViC GraphQL — with API key client
requests-per-second
raised
A free API key exempts the caller from the default anonymous ceiling. The operator does not publish the keyed number, so none is recorded here. High-throughput and continuous consumers are directed to CIViCpy rather than the live endpoint.
OAI-PMH harvesting — WashU Scholarly Repository client
policy
not published
No numeric limit. The Identify response carries a data policy: full content may not be harvested by robots without prior written approval, while metadata is explicitly open to commercial and non-commercial service providers.
WashU enterprise APIs (MuleSoft Anypoint) client
unknown
not published
Access is granted per integrator through a ServiceNow request; any applicable policy is issued with that grant and is not publicly documented.

Policies

Backoff Strategy
Honor Retry-After on 429 and back off exponentially with jitter. For CIViC, stay under 3 req/s unless holding a key, and prefer CIViCpy or a data release for bulk work.
Polite Harvesting
OAI-PMH harvests should use resumption tokens, run off-peak, and respect the repository's robots policy on full content.
