### Using custom Swap API endpoints

You can set custom URLs via the configuration for any self-hosted Jupiter APIs, like the [V6 Swap API](https://station.jup.ag/docs/apis/self-hosted) or [Paid Hosted APIs](https://station.jup.ag/docs/apis/self-hosted#paid-hosted-apis) Here is an example:

```
JUPITER_API_BASE_URL=https://quote-api.jup.ag/v6/
```
