# World Sim Checkout Arrival

`GET /modules/world-sim/checkout/{ref}`

## Request

- Base URL: `https://api-docs.session-exchange.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api-docs.session-exchange.com/modules/world-sim/checkout/{ref}`

#1130: the World-Sim behind the caller's own checkout `ref` — the post-purchase page polls this
until `stage` is `ready`, then focuses that instance. Owner-only: the caller must resolve to a
user (`acting_user_id` — a signed-in human, or a machine token bound to that user; a library
token is refused), and only that user's own checkout and instances are ever read. Anyone else's
ref is a 404, like the checkout status.

## Path parameters

- `ref` string, required

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
