ElevenLabs Music API (via ZeroClick)
ElevenLabs Music API (via ZeroClick) is a paid API for AI agents from api.zeroclick.ac, paid per call via MPP, price unknown, status unknown (last checked 2026-09-15).
Generates original music audio files from a natural-language prompt or structured composition plan, returning base64-encoded MP3/WAV audio with a song identifier.

How this service works
Use this listing when an agent needs programmatic music generation. Supply either a natural-language 'prompt' or a structured 'composition_plan' (they are mutually exclusive). Validate response headers for 'song-id' and 'content-type'. If a timeout or upstream 5xx occurs, mark the call as failed and follow refund policy. Avoid sending copyrighted requests without rights. Refer to upstream docs for supported output_format values and limits. Use when: Generate short to long musical pieces programmatically (3s–600s).; When you need deterministic runs (use seed) or repeatable composition via composition_plan.; When different output formats (mp3/wav) are required for downstream playback or processing. Do not use when: When you need to reproduce an existing copyrighted song without rights or license.; For transient prompts that do not require an external audio artifact (text-only effects).; When the buyer requires guaranteed artist-identical vocals or licensed commercial samples without appropriate rights. Failure modes: Invalid buyer input (e.g., mutually exclusive fields provided).; Upstream rate limiting or 429 responses.; Upstream 5xx service failure.; Payment authorization failure.; Generation timeout (exceeds 30000 ms configured timeout). Price: 0.05 USDC per request.
Output
Returns a JSON object containing base64-encoded audio bytes (bodyBase64), the byte length of the audio, the MIME type (e.g. audio/mpeg or audio/wav), and response headers including a unique song-id and content-type assigned by ElevenLabs.
Example use cases
Example prompt
“Generate me a 45-second instrumental lo-fi hip-hop track — calm and relaxed mood, no vocals — and give it to me as an MP3 file; use seed 42 so I can reproduce it later.”

Endpoint
POSThttps://api.zeroclick.ac/mpp/elevenlabs-music-api-vq4khsWhen to prefer
Choose this endpoint when you need to programmatically generate original music audio files (3 seconds to 10 minutes) via ElevenLabs' music_v1 model, especially when you want to pass a natural-language prompt or a detailed composition plan, require specific output formats (MP3/WAV), need deterministic/reproducible generation via a seed, or want C2PA provenance signing. Avoid if you need licensed commercial samples or copyrighted song reproduction.
Side effects
- Mutually exclusive fields provided (both prompt and composition_plan) — validation error
- Upstream rate limiting (429) from ElevenLabs
- Upstream service failure (5xx) — refund policy applies
- Payment authorization failure
- Generation timeout exceeding 30,000 ms
- Unsupported output_format value
- music_length_ms outside 3000–600000 ms range
Input
Schema · Request body
| Field | Type | Description |
|---|---|---|
| seed | — | Optional random seed (0..2^31-1). When provided, generation may be deterministic. Do not provide together with prompt for seed-only workflows. |
| prompt | — | Natural-language prompt to guide the music generation (up to 4100 chars). Mutually exclusive with composition_plan. |
| model_id | string | Model identifier. Currently only 'music_v1' is supported by the upstream API. |
| output_format | string | Desired audio format (e.g. 'mp3_44100_128', 'wav_48000'). Use formats supported by the upstream service. |
| sign_with_c2pa | — | If true and supported by upstream, attach a C2PA provenance signature to the artifact. |
| music_length_ms | — | Requested length in milliseconds (3,000–600,000). If omitted, the model will choose a suitable length. |
| composition_plan | — | Structured composition plan describing sections, instruments, tempo, etc. Mutually exclusive with prompt. |
| force_instrumental | — | Request instrumental output where feasible (reduce or avoid vocals). |
| store_for_inpainting | — | When true, instructs upstream to retain an artifact for potential inpainting workflows if supported. |
| respect_sections_durations | — | When composition_plan is provided, attempt to respect specified section durations. |
