ElevenLabs

Los modelos de ElevenLabs se llaman a través de una API de trabajos asíncrona y unificada. Inicia una tarea con POST /api/generate y luego sondea GET /api/generate/{taskId} hasta que termine. Esta familia expone 4 endpoints.

Resumen

Todos los endpoints comparten la misma envoltura — solo cambian model y los campos input. Ejecuta cualquiera desde el playground del Mercado de modelos.

Autenticación

Crea una API key en /api-keys y luego envíala como token Bearer. Las solicitudes desde el navegador con sesión iniciada también funcionan mediante la cookie de sesión.
