Lacuna Music

Generate original music from a text description — background beds and soundtrack loops for video, podcast, game and ad workflows, and full vocal songs when you supply lyrics. Every finished task returns hosted MP3 URLs, so an agent can hand the audio straight to the next step. **Tools** - `generate_music` — queue a generation and return the task id immediately - `get_generation` — read a task's status and, once ready, its audio URLs (free, no credits) - `list_models` — available models with their credit cost and takes per request Generation takes a few minutes, so `generate_music` returns a `pending` task rather than blocking. Poll `get_generation`, or subscribe to the `job.completed` webhook. **Models** - **Aether** — two takes per request, widest style range, accepts vocal register and negative tags - **Echo** — one take with a complete song structure of up to three minutes **Getting started** Create an API key at [lacuna.fm/profile/api](https://www.lacuna.fm/profile/api).
