# What does Curbi cost?

Local checks and six public read-only MCP tools are free. Managed Check API costs $1 per 1,000 checked replies in USD, billed monthly. Each reply in a batch counts separately. The current safety limit is 100,000 replies per key per calendar month, not an account-wide spend cap. No SLA is included. Production action signing remains off.

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`.
