# Account

> Your project: one per account. Check identity with GET /project, then billing and limits.

Everything you create — runs, browsers, profiles, files — belongs to your **project**. There is one project per account, and your API key identifies it. Create and manage keys at [cloud.browser-use.com](https://cloud.browser-use.com/settings?tab=api-keys\&new=1).

## Check your project

`GET /project` is the "who am I" call — a cheap way to validate an API key and see which project it belongs to.

```bash curl theme={null}
curl https://api.browser-use.com/api/v1/project \
  -H "X-Browser-Use-API-Key: $BROWSER_USE_API_KEY"
```

```json theme={null}
{
  "id": "prj_abc123",
  "name": "my-project",
  "createdAt": "2026-07-01T12:00:00Z"
}
```

A `404` means the key doesn't map to a project — check the key.
