# Fast (~250 ms) first pass of the website and app safety checks

`POST /user/fast-safety-check`

## Request

- Base URL: `https://api.focusbear.io` (the document declares no server; this is the origin it was published from)
- URL: `https://api.focusbear.io/user/fast-safety-check`
- Auth: HTTP bearer

Send the same body as /user/is-url-safe-to-use (target "url") or /user/is-app-safe-to-use (target "app"). allow=true: let the user through without the full check. allow=false: blur and call the full check, which decides and gives the reason. Any failure here returns allow=false, so the full check stays the fallback.
