Npr Rate Limits

NPR does not publish numeric per-second or per-minute rate limits for its developer APIs. Access is controlled at the OAuth client / partner level; misuse is handled via account suspension per the NPR API Terms of Use rather than a documented 429 throttle ceiling.

Policies

OAuth required
Most NPR API surfaces require an OAuth 2.0 client credential issued via the developer registration flow.
Terms of Use
Use is governed by the NPR API Terms of Use; abuse, misattribution, or content-license violations result in suspension rather than throttling.
Backoff
Clients should implement exponential backoff with jitter on 429 responses and honor any Retry-After header.
