Image Actions
Midjourney action endpoint (upscale/variation/reroll, etc.)
Runs an action on a finished task (status must be SUCCESS): UPSCALE, VARIATION, REROLL, PAN, ZOOM, etc. A new task ID is returned, so poll Query Task Result again for the new outcome.
Billing models
This endpoint is billed per action: mj_upscale, mj_variation, mj_reroll, mj_high_variation, mj_low_variation, mj_pan, mj_zoom. Configure group prices for the relevant models on the channel.
Prerequisites
taskId must belong to the current caller and the original task must be finished (status of SUCCESS). The action reuses the original task's channel; if that channel is disabled the action cannot run.
