POST
Blend
You can also submit through the unified task endpoint POST /v1/task/submit with model set to midjourney-blend and the parameters inside input. Both behave and bill the same.
The response carries a task ID. Fetch the result with Get Task, or pass notify_hook when submitting. When the task succeeds, actions in the result lists what you can do next through Image Actions.
