Midjourney API v2 has been updated:

• Upscaled image URLs are now available in the imageUx array. There is no longer a need to execute POST jobs/seed_async to retrieve upscaled images.
• When using --video upscaled video URLs are now available the videoUx array.
  See both videoUx and imageUx in GET jobs/jobid.
• Prompt length for POST jobs/imagine has been extended from 2048 to 5000 characters.

⚠️ Security consideration when using videoUx and imageUx URLs:
URLs in both arrays follow this format: https://cdn.midjourney.com/<GUID>/…. They contain a job GUID which can be traced back to your account and will expose your account details such as your Discord account name and email. Exercise caution when posting these URLs publicly. You may want to save the URL content locally and serve it from your own origin, or proxy the links to obfuscate the original URLs.

Example

• Midjourney /imagine command POST jobs/imagine

https://…/bird.webp

curl --location 'https://api.useapi.net/v2/jobs/imagine' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer user:12345-…' \
--data '{
    "prompt": "https://…/bird.webp Tweety Bird spins kettlebell with one hand around once and hurls the kettlebell directly at the camera in a slow motion --iw 2 --ar 3:2 --motion low --video"
}'
