# Toggle raw-payload capture for a Dojo run (Mnemom staff).

`POST /sim/{session_id}/capture`

## Request

- Base URL: `https://api.mnemom.ai/v1`
- URL: `https://api.mnemom.ai/v1/sim/{session_id}/capture`
- Auth: HTTP bearer

Sets the session's `capture_payloads` flag. When ON, the runner records `debug`-kind SimEvents carrying the raw outbound model request envelope + latency for the staff debug export (`GET /sim/{id}/export?audience=debug`). Default OFF (faithful 'sim user state'). Read fresh by the runner each tick, so a toggle takes effect on the next turn. Mnemom-staff ONLY. MNE-692.

## Path parameters

- `session_id` string, uuid, required

## Request body

- object
  - `enabled` boolean, required: True to record raw model payloads for this run; false to stop.

## Response `200`

Capture flag updated.

- object
  - `ok` boolean
  - `session_id` string, uuid
  - `capture_payloads` boolean

## Other responses

- `400`: Bad request
- `401`: Authentication required
- `403`: Forbidden
- `404`: Resource not found
- `429`: Rate-limit exceeded. The global per-IP limiter (100 requests/minute, applied to every `/v1/*` route) rejected this request. Back off until the window resets — `Retry-After` carries the cooldown in seconds and `X-RateLimit-Reset` the absolute reset time.
- `500`: Server error — request was well-formed but the server failed to fulfill it. Typically a downstream dependency (DB / RPC / external API) returned an unexpected error.
