# What is the Curbi Sandbox?

A browser workspace at /sandbox/ for building and breaking a policy: run real Check API calls, see the exact text each finding points to, keep request history, and download the result as a runnable CI regression test. Workspaces live in your browser only; there are no hosted accounts yet.

- [Open the Sandbox](https://curbi.io/sandbox/)
- [Policy Check](https://curbi.io/check/)

Updated 2026-10-27. Public access.

## Try a configured check

This public example checks a reply against a configured price; it does not authorize an action or establish a provider outcome.

```sh
curl -sS https://api.curbi.io/v1/check \
  -H 'Content-Type: application/json' \
  -d '{"policy":{"prices":[{"item":"Starter","amount":49}]},"reply":"Starter is $99."}'
```

Expect `pass: false` with `price:mismatch`.

Next: [install a framework adapter](https://curbi.io/connect/) or [start with a working policy](https://curbi.io/policies/).
