# Liquid.tf Developer API

The Liquid.tf API allows you to programmatically manage your listings, buy orders, and trades on the Team Fortress 2 marketplace.

## Base URL

All API endpoints are accessed via:

```
https://api.liquid.tf
```

<Warning>
  **Important:** Only `/api/dev` endpoints are authorized for developer use. Using any other API endpoints for development purposes can result in permanent revocation of your API keys and a ban from the site.

  That said, we are happy to work with developers to tailor solutions that we deem a benefit to our users and the wider community. Contact us at [support@liquid.tf](mailto:support@liquid.tf) to discuss your use case.
