For the complete documentation index, see https://buildwithfern.com/learn/llms.txt. ## 2.16.0 **`(feat):`** Add support for per-endpoint auth routing. When the API-level auth requirement is `ENDPOINT_SECURITY`, each endpoint now applies only the auth scheme(s) it declares in its IR `security` field (OR across the list of requirements, AND within a requirement, and no auth when `security` is empty), instead of applying every configured credential to every request. Behavior for the `ALL` and `ANY` auth requirements (the common cases) is unchanged.
