API v1 is deprecated. This version is no longer being developed — new endpoints, parameters and models are added to v2 only. Use the v2 endpoints to stay current: v2 API documentation.

Text-to-Music generates music tracks from text descriptions. You can control genre, tempo, key, time signature, and even provide lyrics. Optionally upload a reference_audio file for style transfer — the model will use it as a stylistic reference for the generated track. The endpoint returns a task ID to track processing status. Ideal for apps needing automated music creation — background tracks, jingles, or full songs with vocals.

Prerequisite: To ensure a successful request, you must first consult the Model Selection endpoint to identify a valid model slug and check specific limits.

Field values worth knowing

These constraints are enforced by validation and are easy to trip over. They are identical on the v2 endpoint, POST /api/v2/audio/music.

Field	Constraint
`lyrics`	Required and must be non-empty, including for instrumental tracks. Omitting it or sending `""` returns `422 The lyrics field is required.` For an instrumental track, send `"[Instrumental]"`.
`timesignature`	Integer only, and only `2`, `3`, `4` or `6` are accepted. A notation string such as `"4/4"` returns `422 The timesignature field must be an integer.` Map the numerator of an x/4 signature (4/4 → `4`, 3/4 → `3`, 2/4 → `2`, 6/8 → `6`); 5/4 and 7/8 cannot be expressed. Omit the field or send an empty value to let the model choose.
`format`	Use `mp3` — the only format the current models actually produce (`info.limits.output_formats`). Anything else returns `422 The selected format is invalid.`
`keyscale`	Free-form string (`"C major"`, `"D minor"`, `"F# minor"`). Not validated against a fixed list — passed to the model as a hint.
`vocal_language`	Free-form string. Both ISO codes (`"en"`) and language names (`"English"`) are accepted. Not validated against a fixed list.

timesignature is validated as an integer, not as musical notation. If you populate it from a UI dropdown offering values like 4/4 or 6/8, convert to the integer before sending — otherwise only the requests that set the field fail, while the rest keep succeeding.

Reference audio requirements (optional):

Supported formats: MP3, OGG, M4A
Maximum file size: 10 MB (default; configurable)
Duration must be within model-specific limits — 5–60 s on the ACE-Step models (info.limits.min_ref_audio_duration / max_ref_audio_duration)

This endpoint uses multipart/form-data content type to support file uploads.

Authorizations

Authorization

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Headers

enum<string>

default:application/json

required

Available options:

application/json

Body

multipart/form-data

Music generation parameters

caption

string

required

Text description of the music to generate

Example:

"upbeat electronic dance music with energetic synths"

model

string

required

The model to use for music generation. Available models can be retrieved via the GET /api/v1/client/models endpoint.

Example:

"AceStep_1_5_Turbo"

lyrics

string

required

Required, and must not be empty. Lyrics for the music. Use "[Instrumental]" for instrumental tracks without vocals — omitting the field or sending an empty string returns 422 "The lyrics field is required."

Minimum string length: 1

Example:

"[Instrumental]"

duration

number

required

Duration in seconds. The accepted range is model-specific - read info.limits.min_duration / info.limits.max_duration for your model from the Model Selection endpoint; a value outside that range is rejected with 422. The turbo models accept 10-300, AceStep_1_5_Base 30-300.

Example:

30

inference_steps

integer

required

Number of diffusion inference steps. The accepted range is model-specific - read info.limits.min_steps / info.limits.max_steps for your model from the Model Selection endpoint; a value outside that range is rejected with 422. The turbo models only accept 8; AceStep_1_5_Base accepts 5-100.

Example:

8

guidance_scale

number

required

Classifier-free guidance scale. The accepted range is model-specific - read info.limits.min_guidance / info.limits.max_guidance for your model from the Model Selection endpoint; a value outside that range is rejected with 422. The turbo models (AceStep_1_5_Turbo, AceStep_1_5_XL_Turbo_INT8) only accept 1; AceStep_1_5_Base accepts 3-20.

Example:

1

seed

integer

required

Random seed. Use -1 for random.

Example:

-1

format

enum<string>

required

Audio output format. One of mp3, wav or flac. Any other value returns 422 "The selected format is invalid." mp3 is recommended for size; wav and flac are lossless and produce much larger result files.

Available options:

mp3,

wav,

flac

Example:

"mp3"

bpm

integer | null

Beats per minute. The accepted range is model-specific - read info.limits.min_bpm / info.limits.max_bpm for your model from the Model Selection endpoint. The ACE-Step models accept 50-200.

Example:

120

keyscale

string | null

Musical key/scale, as a free-form string (e.g. "C major", "F# minor", "D minor"). Not validated against a fixed list — the value is passed to the model as a hint.

Example:

"C major"

timesignature

enum<integer> | null

Time signature, as the number of beats per bar. Integer only — one of 2, 3, 4 or 6. Musical notation strings such as "4/4" or "3/4" are rejected with 422 "The timesignature field must be an integer." Map the numerator of a x/4 signature to this field (4/4 -> 4, 3/4 -> 3, 2/4 -> 2, 6/8 -> 6). Signatures that cannot be expressed as 2, 3, 4 or 6 (e.g. 5/4, 7/8) are not supported. Omit the field or send an empty value to let the model choose automatically.

Available options:

2,

3,

4,

6

Example:

4

vocal_language

string | null

Language for vocals, as a free-form string. Both ISO codes ("en", "es", "fr") and language names ("English") are accepted. Not validated against a fixed list — the value is passed to the model as a hint.

Example:

"en"

reference_audio

file | null

Optional reference audio file for style transfer. Supported formats: mp3, ogg, m4a. Max size configurable (default 15MB). Duration must be within model-specific limits.

webhook_url

string<uri> | null

Optional HTTPS URL to receive webhook notifications for job status changes (processing, completed, failed). Must be HTTPS. Max 2048 characters.

Maximum string length: 2048

Example:

"https://your-server.com/webhooks/deapi"
