Clarivate Rate Limits

Clarivate publishes per-second and per-day request ceilings for the five Web of Science / InCites APIs, tied to entitlement plan rather than to a paid tier. It does NOT document any rate-limit response header, any 429 behaviour, or any Retry-After contract — so an agent can read the number in the docs but gets no runtime signal back from the gateway. This file replaces a 2026-05-04 scaffold that asserted X-RateLimit-* / RateLimit-Policy headers and 429/503 codes Clarivate has never documented.

Clarivate Rate Limits is the machine-readable rate-limit profile for Clarivate on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 13 rate-limit definitions, across the Free Trial Plan, Free Institutional Member Plan, Free Institutional Integration Plan, Basic, and Intermediate tiers, measuring requests_per_second and requests_per_day.

The profile also includes response codes documented for documented and note.

Tagged areas include Analytics, Bibliometrics, Citations, Data, and Drug Pipeline.
