Listenarr API documentation

This page renders the bundled OpenAPI snapshot as a read-only endpoint reference. Listenarr's built-in Swagger UI is currently enabled only for Development builds, so this docs site is the reliable reference for normal installed instances.

Use Swagger in a local development instance

Listenarr mounts Swagger only when the app runs in Development. By default the API listens on port 4545, unless you override it with --urls, so the built-in Swagger UI is usually available at /swagger/ on that same origin.

Normal installed or production-style instances do not expose /swagger/ by default.
