# Upload Audio

> Upload audio files to get URLs for use in audio-related APIs

<Note>
  **Note for users in mainland China:** Please use `https://toapis.cn` as the API endpoint (Base URL). Replace `https://toapis.com` with `https://toapis.cn` in the examples in this document.
</Note>

<Note>
  **The docs Playground does not support file uploads**: Please use the cURL, Python, or JavaScript code examples below for testing.
</Note>

## Why Upload Audio First?

1. **Unified input flow** - Upload local audio once and reuse the returned public URL
2. **Less repeated transfer** - The same uploaded audio can be reused in multiple requests

## Authorizations

<ParamField header="Authorization" type="string" required>
  Use Bearer Token for authentication

  Get your API Key: Visit [API Key Management](https://toapis.com/console/token)

## Body

  Audio file

  **Supported formats:**

  * MP3 (.mp3)
