Suno v6 API

Generate complete songs — vocals, lyrics and instrumentals — through one asynchronous REST endpoint. The chirp-v6 family covers the flagship Suno v6 model, a fast economical tier and a more experimental variant, billed per request in credits.

10–12 credits per song · 1 USD = 100 credits

What the Suno v6 API gives you

The Suno v6 API lets a server-side application create full songs from a text prompt or custom lyrics. You pick a model from the chirp-v6 family, send one POST request, and receive a workId for an asynchronous task — vocals, structure and instrumentation are produced for you.

Three current models share the same endpoint. chirp-v6 is the flagship for production releases. chirp-v6-mini is the fast and economical tier for high-volume or prototype workloads. chirp-v6-wild is the more experimental variant when you want looser, more adventurous arrangements. Every result reports the model that actually produced the audio in model_name, so you can migrate legacy integrations safely.

Quickstart: create and poll a task

Send an authenticated POST to /v2/generate, save the returned workId, then poll /v2/feed until the task completes — or pass callback_url and wait for the webhook.

curl
curl -X POST "https://udioapi.pro/api/v2/generate" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "chirp-v6",
    "prompt": "Verse 1: Walking down the street, feeling so free\nChorus: Summer dreams are calling me",
    "style": "pop, upbeat, electronic, 120 bpm",
    "title": "Summer Dreams",
    "make_instrumental": false
  }'

curl -X GET "https://udioapi.pro/api/v2/feed?workId=YOUR_WORK_ID"

Generation is asynchronous. Poll every 5–10 seconds with a bounded timeout, and download the audio URLs promptly — media links are temporary.

Suno v6 models and pricing

All three models are available on generate, upload-cover and extend. Prices are per request; 1 USD buys 100 credits.

ModelCredits≈ USDPositioning
chirp-v612≈ $0.12Flagship — highest-fidelity songs for production releases
chirp-v6-mini10≈ $0.10Fast and economical — batch jobs and prototyping
chirp-v6-wild12≈ $0.12More experimental — adventurous arrangements

Legacy identifiers keep working at their historical price: chirp-v5 and chirp-v5-5 are served by chirp-v6; chirp-v3-5, chirp-v4-0, chirp-v4-5, chirp-v4-5-plus and chirp-v4-5-all are served by chirp-v6-mini. Omitting the model field bills the 5-credit base tier served by chirp-v6-mini.

What you can build on it

The same account and API key unlock the documented audio endpoints.

Text and lyrics to song

Custom Mode for lyrics, style and title, or Inspiration Mode from a plain description. Optional image_urls steer the mood.

Extend an existing track

Continue a generated song with inherited settings or a new prompt, then pick up the result from the feed.

Cover your own audio

Upload audio and produce a cover version through the upload-cover endpoint.

How it works

From API key to a playable track in four steps.

  1. 1

    Create an API key

    Sign in, open the dashboard and copy a key. Keep it in a server-side secret — never in browser code.

  2. 2

    Submit the task

    POST /v2/generate with your model and prompt. The response returns a workId for the asynchronous job.

  3. 3

    Poll or receive a callback

    GET /v2/feed?workId=... every 5–10 seconds, or pass callback_url and handle the completion webhook.

  4. 4

    Download the audio

    On SUCCESS the feed response contains temporary audio URLs. Store the files on your own storage.

Simple credit pricing

1 USD converts to 100 credits. A chirp-v6 song costs about $0.12 and a chirp-v6-mini song about $0.10 — you pay only for the model you pick, with no seat or subscription required for API access.

Pay-as-you-go credits never expire. Rejected or failed requests are refunded automatically.

Limits and notes

  • All generation endpoints are asynchronous; the POST response contains a workId, not audio.
  • Poll /v2/feed with bounded retries, or use callback_url for server-to-server delivery.
  • chirp-v5 and chirp-v5-5 requests produce chirp-v6 audio; earlier legacy identifiers produce chirp-v6-mini.
  • Media URLs are temporary — download and persist outputs to your own storage.
  • Keep prompts, titles and styles within the documented limits; longer values are truncated.

Suno v6 API FAQ

Answers about models, billing and the asynchronous workflow.

Is this the official Suno API?

No. udioapi.pro is an independent third-party API service with its own endpoints, accounts, credits, terms and support. It is not affiliated with, endorsed by, or operated by Suno or Udio.

Which Suno v6 model should I start with?

Use chirp-v6-mini for prototyping and high-volume work — it is the fast, economical tier at 10 credits. Switch to chirp-v6 (12 credits) when you need flagship quality, or chirp-v6-wild for more experimental output.

How much does a request cost?

chirp-v6 and chirp-v6-wild cost 12 credits per request and chirp-v6-mini costs 10. At 1 USD = 100 credits that is roughly $0.10–$0.12 per song. Omitting the model field bills the 5-credit base tier served by chirp-v6-mini.

How do I get the generated audio?

Every accepted request returns a workId. Poll GET /v2/feed?workId=... every 5–10 seconds until the status is SUCCESS, or pass callback_url to receive a webhook. The feed response then contains the audio URLs.

Do my old model identifiers still work?

Yes. chirp-v5 and chirp-v5-5 are served by chirp-v6, and chirp-v3-5 through chirp-v4-5-all are served by chirp-v6-mini — each at its historical price. model_name reports the model that produced the audio.

Can I extend or cover a generated song?

Yes — the chirp-v6 family is available on generate, upload-cover and extend. Extensions are billed at the original track's model price, and rejected or failed requests are refunded.
