Suno API FAQ
The questions that decide whether an integration works are rarely about the model; they are about keys, tasks and money.
Quick answers
| Question | Short answer |
|---|---|
| Is there an official key? | No public official key; keys come from the third-party platform. |
| What does a generation cost? | 0.6 CNY per generation, two tracks; reads are free. |
| Why is audio empty? | The task is still pending; poll until terminal. |
| Do failed tasks cost? | No; failed tasks are refunded. |
| Do download URLs expire? | Yes; fetch a fresh URL, no regeneration fee. |
| Can I run many at once? | Yes, with a queue and an in-flight cap. |
Where to go next
For the first request, use the Python or Node.js example. For production, read limits, task lifecycle, batch generation and audio storage.
常见问题 / FAQ
Is there an official Suno API key?
No public official key is issued. The usable integration is a third-party HTTP API with its own key and billing.
Why do I get 429?
You are sending bursts or too many parallel generations. Back off, queue, and cap concurrency.
Why does my media URL stop working?
It is temporary. Query the task again or call download-url for a fresh link; no new generation is needed.
Are failed tasks charged?
No. They are refunded; check the task status before retrying.
Can I use the API from a browser?
No. A browser key is visible to visitors; proxy through your server.
Can I resell the API?
That is a commercial and contract question, not a technical one; confirm it with the platform before building a resale product.
