## 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.

Parameters

Name	In	Type	Required	Description
output_format	query	string	No	Output format of the generated audio. Formatted as codec_sample_rate_bitrate. So an mp3 with 22.05kHz sample rate at 32kbs is represented as mp3_22050_32. MP3 with 192kbps bitrate requires you to be subscribed to Creator tier or above. PCM with 44.1kHz sample rate requires you to be subscribed to Pro tier or above. Note that the μ-law format (sometimes written mu-law, often approximated as u-law) is commonly used for Twilio audio inputs.
enable_logging	query	boolean	No	When enable_logging is set to false zero retention mode will be used for the request. Zero retention mode may only be used by enterprise customers.
videos	body	string[]	Yes	One or more video files sent via FormData array (multipart/form-data). They will be combined into one codec in order. A maximum of 10 videos is allowed, where the total size of the combined video is limited to 200MB. In total, the video can be up to 600 seconds long. Note that combining multiple videos may increase the request duration significantly. If possible, combine the videos beforehand.
description	body	string	No	Optional text description of the music you want. A maximum of 4100 characters is allowed.
tags	body	string[]	No	Optional list of style tags (e.g. ['upbeat', 'cinematic']). A maximum of 10 tags is allowed.
model_id	body	string	No	Request body field model_id.
add_sfx	body	boolean	No	When true, incorporate SFX cues from the video.
separate_tracks	body	boolean	No	When true, return a ZIP with separate music and SFX audio tracks instead of a single mixed file. Use this for more flexibility to layer the tracks.
use_audio_as_reference	body	boolean	No	When true, analyze the video's audio track and use its genres, BPM, instrumentation, mood, and arc as reference characteristics for music generation.
sign_with_c2pa	body	boolean	No	Whether to sign the generated song with C2PA. Applicable only for mp3 files.
