How many songs does one Suno AI request produce?

Generation-class Suno AI operations return two complete track variations per request — each with its own audio URL, lyrics, duration and style tags — so one flat charge covers both takes.

What is the difference between inspiration and custom mode?

Inspiration mode (customMode: false) takes a short description and Suno AI writes the lyrics for you. Custom mode (customMode: true) uses your prompt strictly as lyrics and requires a style and title, giving you full editorial control. Instrumental mode skips vocals in either path.

How do I edit a Suno AI song I already generated?

Save the task id and the track id from output.tracks[].id. Extension, section replacement, stem separation, WAV conversion, MIDI, cover art and music video all take those ids — you never need to re-upload your own Suno AI generations.

Can I use my own audio with Suno AI?

Yes. The upload-cover, upload-extend, add-vocals, add-instrumental and mashup operations take public HTTP(S) URLs of your own audio files (up to eight minutes) and run the same Suno AI pipeline on them.

How does Suno AI voice cloning work?

Submit a recording to voice-validate and receive a validation phrase. Record yourself reading it, submit that to voice-generate, and you get a reusable voice id. Pass it as personaId with personaModel voice_persona in any Suno AI generation.

How is Suno AI priced on reAPI?

Flat per-request credits at 1 credit = $0.001 — generation-class operations share one rate that covers both returned tracks, and every editing or asset operation has its own flat rate. No subscription; see the pricing table above for current numbers.

Do my generated files expire?

No. Finished audio, video and artwork are rehosted to reAPI's storage when the task completes, so the URLs in your Suno AI task output remain stable instead of expiring after an upstream retention window.

Is Suno AI free or paid?

Paid. Completed generations are charged at the rates in this page's pricing table. Eligible new accounts may receive promotional test credits; availability and amount are shown at signup or in the dashboard. Technical or provider failures are refunded automatically, except where this page documents a charged output-moderation block.

Does Suno AI require a monthly subscription?

No. Pricing is pay-as-you-go: $1 buys 1,000 credits and credits never expire. Cost scales with what you generate rather than with a recurring fee.

How do I get a Suno AI API key?

Sign up and create a key in the dashboard, no card required. Pass it as a Bearer token in the Authorization header.

Suno AI — Full-Song Music Generation & Editing

Run the complete Suno AI toolchain through one pay-per-use platform.

The whole Suno AI studio behind one task API

Suno AI on reAPI is not a single text-to-music endpoint — it is the full production suite. Every Suno AI request returns two complete tracks with vocals, lyrics, style tags and per-track ids, and those ids unlock the rest of the chain: continue a song from any second, re-imagine an uploaded demo in a new style, sing fresh vocals over a backing track, blend two songs into one, rewrite a single section, or pull the whole thing apart into stems. Suno AI versions V4 through V5.5 are selectable per request — V5 generates dramatically faster and holds song structure from a 30-second hook to an 8-minute epic — and finished audio is rehosted on stable storage so your URLs do not expire. You pay per request with transparent credits: no seat licenses, no monthly plan, just Suno AI on demand.

What you can build with this model

Real-world workflows and production use cases you can build and ship with this model.

A voice dissolving into a luminous Suno AI waveform

Turn one line into a finished Suno AI song

In inspiration mode you give Suno AI a single sentence and get back two fully produced tracks — verses, chorus, vocals and style tags included. Switch to custom mode when the words matter: your text becomes the exact lyrics that Suno AI sings, with style and title under your control and up to 5,000 characters of lyrics on V4.5 and V5. Instrumental mode drops the vocals entirely for beds, intros and background scores, and songs run up to 8 minutes per generation on V4.5 and above.

Generate a song

Keep working the Suno AI track, not just generating it

Every track you generate with Suno AI carries an id that the editing operations understand. Extend a song from any timestamp when the demo ends too early. Upload an existing recording and let Suno AI cover it in a new genre — or extend it in its original style. Replace one section's lyrics without touching the rest. Add vocals to an instrumental, add instrumentals under a vocal stem, or mash two uploads into one track. It is the Suno AI workflow you know, driven entirely by API calls.

Ship Suno AI production assets, not just previews

When the song is right, Suno AI hands you the deliverables: lossless WAV conversion, vocal separation from a simple two-stem split to a full multi-stem breakdown with named instruments, MIDI note data for your DAW, generated cover art, and a rendered music video with your own credit line. The Suno AI voice-cloning flow captures a singing voice from a recording and returns a reusable voice id for future generations.

Why reAPI

Every Suno AI operation, one integration

Eighteen asynchronous operations and four instant helpers cover the entire Suno AI surface — generation, extension, covers, mashups, section replacement, stems, WAV, MIDI, music videos, sound effects, lyrics and voice cloning — all through one task API with one billing model.

Two tracks per request, ids that chain

Each Suno AI generation returns two variations with lyrics, duration and style tags, plus per-track ids that plug straight into the downstream operations. Build automated pipelines where a generated song flows into stems, WAV masters and a music video without leaving the API.

Pay per request, keep your files

Flat per-request pricing in credits — no Suno AI subscription tiers, no expiring quotas. Finished audio is rehosted on reAPI's storage, so the URLs in your task results stay valid instead of timing out after a vendor retention window.

Suno AI vs Udio

Both generate impressive music from text, but they are built for different worlds: Udio is a subscription web app that has moved into a streaming-only licensed ecosystem, while Suno AI on reAPI is a full programmable toolchain you drop into your own product.

Ship your first Suno AI track in minutes

step 01
Create an API key
Sign up, open Settings → API Keys, and mint a key. New accounts include free credits — enough to generate several complete Suno AI songs before topping up.
Open
step 02
Generate in the playground
Pick an operation chip, describe the song (or paste exact lyrics in custom mode), choose a Suno AI version and submit. The playground polls the task and plays both finished tracks inline.
Open
step 03
Move it into code
Copy the request from the docs: POST /api/v1/audio/generations with model suno-music, then poll /api/v1/tasks/:id. Save output.tracks[].id — that id drives every follow-up Suno AI operation.

Task failed or timed out

A task that reaches a failed state is never charged — the reserve refunds automatically. Keep the task id and retry when ready.

Frequently asked questions

Common questions about this model.

Every generation request selects a Suno AI version explicitly: V4, V4.5, V4.5+, V4.5-ALL, V5 or V5.5. V4 caps songs at four minutes; V4.5 and V5 reach eight. Add-vocals and add-instrumental run on V4.5+ and newer, and sound effects use V5 or V5.5.
