# API

### Site & base URL

* **Web:** <https://www.empirebuilder.world>

Use the **same origin** for API calls:

```txt
https://www.empirebuilder.world/api/…
```

Example:

```bash
curl -s "https://www.empirebuilder.world/api/top-empires"
```

(Some environments also resolve the apex hostname `empirebuilder.world`; prefer **`www`** for consistency unless your integration relies on another host.)
