There is no public developer portal or API reference to read limits from — the only public statement about the API is a pricing-card feature line ("Open API and custom integration", Ultimate+ tier only). Live unauthenticated responses from api.giveffect.com were inspected directly and carry no rate-limit headers of any family. limit_count: 0 limits: [] headers: observed: [] note: >- Response headers observed live on GET https://api.giveffect.com/ (200) and GET https://api.giveffect.com/v1/donors (404) on 2026-08-13 were: Server, Date, Cache-Control, X-XSS-Protection, X-Request-Id, X-UA-Compatible, ETag, X-Frame-Options, X-Runtime, X-Content-Type-Options, X-Powered-By, Status, Content-Type.
