# ElevenLabs Music v2 Needs prompt and music length ms. Served by fal.ai. Elevenlabs Music v2, served by fal.ai. The OpenAPI schema for the elevenlabs/music/v2 queue. Price: Your request will cost $0.6 per output audio minute. The audio will be rounded up to the closest minute. For instance, a generation with 30 seconds output will be billed as 1 minute.

Replace example values with the user’s requested inputs, respecting the schema; do not execute an example merely to test a connection. ```json { "tool_id": "fal/elevenlabs-music-v2", "input": { "prompt": "Mysterious original soundtrack, themes of jungle, rainforest, nature, woodwinds, busy rhythmic tribal percussion.", "output_format": "mp3_48000_192", "music_length_ms": 60000 } } ``` ## Execute and retrieve Inspect again before execution, explain the price and obtain the required authority. Use MCP run_tool or POST /v1/run with this tool ID, valid input and an idempotency key. Save the returned run ID and follow the actual state. If Agentik answers that the tool is temporarily unavailable, do not retry it blindly; use discovery to propose an alternative. This tool uses deferred settlement. Follow its returned task/run instructions; preserve the existing reservation until the result is reconciled. A partial or uncertain result can still have consumed provider resources. Consult [billing](/docs/billing.md), [idempotency](/docs/idempotency.md) and [asynchronous results](/docs/async.md).
