Referencing source tracks: mashup requires exactly 2 source tracks—specify them via task_ids (an array of exactly 2 of ythe task_ids), with optional audio_indexes (a parallel array selecting which item in each task’s music[], 1-based, default 1 for both).
custom determines which fields take effect. All submitted fields must still meet their type, range, and length requirements, even when they do not take effect in the current mode. With custom=true, prompt (lyrics), title, tags, negative_tags, auto_lyrics, style_weight, weirdness, audio_weight, and persona_id take effect, while gpt_description is ignored. With custom=false, only gpt_description is used; it is required, and omitting it returns 400 during submission. vocal_gender takes effect in both modes. If custom is omitted, the backend infers it in this order: prompt present → true; no prompt but gpt_description present → false; otherwise, tags or title present → true.

Body

string
default:"suno"
Audio model. Currently pass suno (defaults to suno if omitted).
string[]
required
Array of ythe task_ids for the 2 source tracks (must be exactly 2; any other count returns 400 directly at submission time).
integer[]
An array parallel to task_ids that selects a track from each task’s data.result.music[] array (1-based; each entry defaults to 1).
boolean
default:"false"
Whether purely instrumental (true=no vocals). If omitted, defaults to false (with vocals).
string
default:"v6"
Public version: v6 / v6-wild / v6-mini. Defaults to v6; omit this field when using custom_model_id.
string
The full UUID returned by the model-creation task. Mutually exclusive with version and persona_id.
boolean
true=custom mode (prompt used as lyrics); false=inspiration mode (uses gpt_description); if omitted, inferred from the content (see the Warning above).
string
Conditionally required: provide lyrics when custom=true && instrumental=false. The field is inactive in inspiration mode, but any submitted value must still meet the length limit.
string
Inspiration prompt. Required when custom=false — if missing, the request fails with 400 at submission (nothing is charged).
string
Title. Only takes effect when custom=true.
string
Style tags. Only takes effect when custom=true.
string
Style tags to exclude. Only takes effect when custom=true.
boolean
true=rewrite the provided lyrics creatively. Only takes effect when custom=true.
number
Style weight, 0.00–1.00 (out-of-range values return 400 directly at submission time). Only takes effect when custom=true.
number
Creativity weight, from 0.00 to 1.00. weirdness_constraint is accepted as a legacy alias; use weirdness for new requests.
number
Audio weight, 0.00–1.00. Only takes effect when custom=true.
string
Vocal gender: Male / Female. Works in both modes.
string
Persona Style ID. Only applies when custom=true is used and mutually exclusive with custom_model_id.
string
Style variation: off / normal / high / extra / max. Optional.
boolean
default:"false"
Enables Max mode. Requires custom mode and is billed at twice the standard price.
string
Output audio format: mp3 / m4a / wav. This endpoint does not support a target-duration field.
Get Result: This is an asynchronous task. After submission, you will receive task_id and then poll GET /v1/music/tasks/{task_id} every 3–5 seconds until status becomes completed or failed (music generation usually takes 30–120 seconds; while generation is in progress, status may be pending or processing, and progress is an integer from 0 to 100 and is not guaranteed to change at fixed intervals). Once completed, read audio_url from data.result.music[]. In case of failure, data.error.message provides the reason and the deducted amount will be automatically refunded.
