Async Generation (MidJourney)

MidJourney returns status: "pending" initially. Poll until complete: 
{
  "id": 18495,
  "status": "pending",
  "model_slug": "midjourney",
  "eta_seconds": 45
}
Then poll: GET /api/v2/generate/{id} See Generation Status for details.

​
Non-square Pricing Note

DALL-E 3 and GPT Image 1.5 charge more for non-square aspect ratios (e.g. 1024×1792 costs up to 2× more). Use the Calculate Price endpoint to check exact token cost before generating.
