- URL: `https://apihub.co.il/v1/ai/music`
- Auth: HTTP bearer

Original, royalty-cleared background music or songs, 3 s – 5 min. Hosted mp3. Send `sections` to time the music to your video: each section lasts exactly its `duration` (a quiet bed under the story, a hit on the reveal, a build before the payoff).

**Billing:** Per second of music · **Rate limit:** 20/min

## Headers

- `Idempotency-Key` string
- `X-Tag` string

## Request body

- object
  - `avoid` string[]: With `sections`: what the whole track must not have
  - `prompt` string: Genre, mood, instruments, tempo — or lyrics. With `sections` it is the overall style
  - `duration` number: seconds (with `sections`: their sum)
  - `sections` object[]: Music timed to your video: consecutive sections, each exactly `duration` seconds — quiet under a story, a hit on the reveal, a build before the payoff
    - `name` string, required: e.g. intro, tension, the reveal, drop, outro
    - `avoid` string[]: What this section must not have
    - `lyrics` string[]: Sung lines (only when instrumental is false)
    - `styles` string[], required: What this section sounds like: instruments, energy, dynamics
    - `duration` number, required: seconds — the section lasts exactly this long
  - `instrumental` boolean
