# API Authentication

Myrouter API uses the Authorization field in `request headers` to carry the API key for authentication. You can view and manage your API keys on the [Settings page](https://myrouter.ai/settings/key-management).

```js theme={null}
{
    "Authorization": "Bearer {{API Key}}"
}
```
