## Critical Gotchas
* Authentication uses the non-standard `xi-api-key` header, not `Authorization: Bearer`. Sending a Bearer token returns HTTP 401.
* Text-to-speech responses are raw binary audio, not JSON. Write the body to a file (`--output speech.mp3`) rather than parsing it.

curl -X POST 'https://api.elevenlabs.io/v1/music/upload' \  -H "xi-api-key: $ELEVENLABS_API_KEY" \  -F '[email protected]' \  -F 'extract_composition_plan=false' \  -F 'with_timestamps=false' \  -F 'with_waveform_visual=false'

Parameters

Name	In	Type	Required	Description
file	body	string	Yes	The audio file to upload.
extract_composition_plan	body	boolean	No	Whether to generate and return the composition plan for the uploaded song. Pass a model id (`music_v1`, `music_v2` or `music_v2_5`) to control which composition plan format is returned. Passing `true`/`false` is deprecated; `true` defaults to the `music_v1` plan format. Enabling this will increase the latency.
with_timestamps	body	boolean	No	Whether to transcribe the uploaded song and return word-level timestamps. If True, the response will include words_timestamps but will increase the latency.
with_waveform_visual	body	boolean	No	Whether to return the visual waveform of the uploaded song.

Response 200 OK
