Metamap Rate Limits

MetaMap does not publish explicit numeric rate limits in its public developer documentation. The API uses an OAuth 2.0 client-credentials flow that issues a one-hour JWT bearer token; concurrency is governed by the per-account verification volume tier negotiated with sales. SDK Cooldown is a product-level throttle that prevents duplicate verifications from the same origin within a configurable window. This document records the throttling surface so consumers know which headers and response codes to expect.
