# Credentials

## Authentication

Use the `accessKey` header on every request.

```http theme={null}
accessKey: <your_api_key>
```

### Example

```bash theme={null}
curl --location 'https://api.myvocal.ai/sound_clone/api/v1/user/info' \
--header 'accessKey: <your_api_key>'
```

### Best practices

* Keep API keys on your backend server.
* Do not expose API keys in frontend clients.
* Rotate keys if leakage is suspected.
