# API Playground

Eagle includes a built-in interactive API playground that lets you test all API endpoints without writing any code. Open it in your browser:

```
http://localhost:41595/api/v2/playground
```

Key features of the playground:

* **Live testing** — Send real API requests against your current Eagle library and see responses instantly
* **GUI parameter input** — Select and fill in parameters through a visual form, no need to manually craft JSON
* **Code snippets** — Each operation automatically generates a JavaScript `fetch` code snippet you can copy and use directly
* **Full endpoint list** — The left sidebar lists all available API endpoints, organized by category

{% hint style="info" %}
The playground operates on your actual library data. Write operations (add, update, delete) will modify your data for real — use with care.
