# Gateway Check

`POST /gateway/check`

## Request

- Base URL: `https://api.os3robotics.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.os3robotics.com/gateway/check`
- Auth: HTTP bearer

Sends one request through your gateway key and reports `ok`, or the first thing that
stops an evaluation (or, with a training `use`, a training) run on its traffic, with what
to do. A refused key is that first failure (`credential`), not a 401.

  - `use` 'eval_only' | 'decider_sft' | 'vla_finetune' | 'distillation' | 'preference_rl'

## Response `200`

Successful Response

- CheckResult
  - `ok` boolean, required
