# Run a follow-up action on a completed Midjourney image

`POST /v2/images/midjourney/action`

## Request

- Base URL: `https://api.apiframe.ai`
- URL: `https://api.apiframe.ai/v2/images/midjourney/action`
- Auth: one of:
  - API key in header `X-API-Key`
  - HTTP bearer

Runs a follow-up action on a completed `midjourney` job, referenced by its job ID. Grid actions — `upsample` (U1–U4) and `variation` (V1–V4) — act on a grid-producing parent; `index` selects which of the 4 images. Upsample actions — `inpaint` (Vary Region, base64 `mask` + optional `prompt`), `outpaint` (Zoom Out, `zoomRatio` 1.5 or 2), and `pan` (`direction` up/down/left/right) — act on a completed upsample job. Upsample returns a single image; every other action returns a fresh 4-image grid (which can itself be acted on). Returns 409 when the requested action is not available for the parent job.

## Headers

- `Idempotency-Key` string

## Request body

- union: Discriminated by `action`. Grid actions (`upsample`/`variation`) take an `index` (1–4) and act on a completed grid job; upsample actions (`inpaint`/`outpaint`/`pan`) act on a completed upsample job.
