Authentication

All API requests require authentication via an API key. You can get your API key from the Atlas Cloud dashboard.

export ATLASCLOUD_API_KEY="your-api-key-here"

HTTP Headers

import os

API_KEY = os.environ.get("ATLASCLOUD_API_KEY")
headers = {
    "Content-Type": "application/json",
    "Authorization": f"Bearer {API_KEY}"
}

Keep your API key secure

Never expose your API key in client-side code or public repositories. Use environment variables or a backend proxy instead.

# suno/chirp-v6-mini

> Suno V6 Mini via APIMart: the lighter, faster V6 variant for drafts and short clips. Same modes and pricing as chirp-v6. Async; returns 2 tracks per generation.


## Overview

- **Submit endpoint (POST)**: `https://api.atlascloud.ai/api/v1/model/generateAudio` — start an async generation; returns a `prediction_id`
- **Poll endpoint (GET)**: `https://api.atlascloud.ai/api/v1/model/prediction/{prediction_id}` — poll this until the prediction finishes
- **Model ID**: `suno/chirp-v6-mini`


## API Information

This model can be used via our HTTP API or more conveniently via our client libraries.
See the input and output schema below, as well as the usage examples.


### Input Schema

The API accepts the following input parameters:

  - Default: `"Late-night city lo-fi piano with the sound of rain"`

- **`custom`** (`boolean`, _optional_):
  false = inspiration mode (prompt is a description). true = custom mode (prompt is used as lyrics, and title / style / negative_tags / auto_lyrics / persona_id / style_weight / weirdness_constraint / audio_weight / duration take effect).
  - Default: `false`

- **`instrumental`** (`boolean`, _optional_):
  Instrumental only, no vocals.
  - Default: `false`

- **`variety`** (`string`, _optional_):
  How much the two takes should diverge from the most predictable rendition of the prompt. off = conservative, max = most adventurous. Works in both modes.

Suno V6 Mini (suno/chirp-v6-mini)

Generate a full song — vocals or instrumental — from a text prompt, powered by Suno v6-mini: the lighter V6 variant — faster turnaround, well suited to drafts and short-form clips. Each generation returns 2 tracks plus cover art.

Two modes

mode	set	`prompt` means
Inspiration	`custom: false` (default)	a description of the song: style, mood, genre, theme
Custom	`custom: true`	the actual lyrics, e.g. `[Verse] ... [Chorus] ...`

In custom mode you can also set title, style, negative_tags, auto_lyrics, persona_id, style_weight, weirdness_constraint, audio_weight and duration. Those fields are silently ignored in inspiration mode. vocal_gender, instrumental and variety work in both modes.

Parameters

field	required	notes
`prompt`	yes	description (inspiration mode) or lyrics (custom mode), ≤3000 chars. Optional only when `custom: true` and `instrumental: true`
`custom`	no	`false` = inspiration (default), `true` = your own lyrics
`instrumental`	no	instrumental only, no vocals
`variety`	no	`off` / `normal` / `high` / `extra` / `max` — how far the two takes stray from the obvious rendition. Both modes. New in V6
`vocal_gender`	no	`Male` / `Female` — both modes
`title`	no	song title — custom mode only
`style`	no	style tags, e.g. `synthwave, female vocal, cinematic` — custom mode only
`duration`	no	target length in seconds, 10–360 — custom mode only. New in V6
`negative_tags`	no	styles to avoid — custom mode only
`auto_lyrics`	no	let the model rewrite your lyrics — custom mode only
`style_weight`	no	0.00–1.00 — custom mode only
`weirdness_constraint`	no	0.00–1.00 — custom mode only
`audio_weight`	no	0.00–1.00 — custom mode only
`persona_id`	no	voice identity id — custom mode only

Output

outputs holds 2 audio URLs (two takes of the same request); the cover art is returned separately in thumbnail so it is never mixed into the audio list.

Notes

Async: submitting returns a request id; poll /api/v1/model/prediction/{request_id} until status is completed or failed. Generation typically takes 30–120s.
Billing: $0.132 per generation (both tracks included) — charged per request, not per track. Failed generations are not billed.
Upgrading from suno/chirp-v5 and the other chirp-v3/v4/v5 models: those engines were retired upstream. The request body is unchanged — swap model to suno/chirp-v6-mini and everything else keeps working.

Example

Inspiration mode:

{
  "model": "suno/chirp-v6-mini",
  "prompt": "Late-night city lo-fi piano with the sound of rain"
}

Custom mode with your own lyrics and a target length:

{
  "model": "suno/chirp-v6-mini",
  "custom": true,
  "prompt": "[Verse]\nMorning light through the kitchen window\n[Chorus]\nSlow down, slow down, the day can wait",
  "title": "Slow Morning",
  "style": "acoustic folk, warm female vocal, gentle guitar",
  "vocal_gender": "Female",
  "duration": 60,
  "variety": "high"
}
