Suno API Limits, Inputs and Production Checks on APIMART

The public APIMART description states: Suno on APIMart: generate full songs with vocals, write lyrics, split stems, cover and remix — all from text through one unified, pay-as-you-go API.

Source-backed production checks

How much does the Suno API cost? Suno is pay-as-you-go: you are billed per generation with no subscription or hidden fees, and your balance works across every model on APIMart. See the pricing section on this page for the current per-operation rates.
What can I create with the Suno API? You can generate full songs with vocals and instrumentals, write lyrics, extend or cover tracks, create mashups, separate stems, add vocals or instrumentals, build a persona voice, export WAV, generate a music video and more — over 30 music operations behind one API.
What audio formats and outputs do I get? Generations return streamable audio URLs along with metadata such as title, duration, tags and cover art. You can also export high-quality WAV and generate a music video for supported operations.

Validate every request field against the linked API reference. Persist task identifiers for asynchronous routes, use bounded polling and backoff, and do not count submission as completed output.

FAQ

What public evidence was checked for Suno?

The live APIMART model page and its linked API reference were checked on September 2, 2026.

Where are accepted inputs and options defined?

Use the linked API reference as the source of truth for request fields, enumerations and incompatible combinations.

How should asynchronous work be measured?

Persist the returned task identifier and count success only after the final task status reports a completed output.

Which failures need separate handling?

Treat validation, authentication, balance, rate-limit and server failures as distinct operational states.

Can public constraints change?

Yes. Recheck the live model page and API reference before shipping or changing a production preset.
