# Populate demo data (only available for demo organizations).

`POST /api/v1/organizations/{id}/populate-demo`

Runs the population off the request thread (a `tokio::spawn`) and returns
`202` immediately — the work is a few hundred sequential DB round-trips and
would otherwise exceed the reverse-proxy request timeout against a remote
database. Poll `GET /{id}/populate-demo/status` for completion/failure.

## Path parameters

- `id` string, uuid, required

## Response `202`

Demo data population started

- ApiResponseDemoPopulateStatus
  - `data` union — Lifecycle of a demo-populate task. `Running` is set synchronously in the POST handler (before the `202`), then flipped to a terminal variant by the spawned task. `Failed` carries the error string so the UI can show why.
