POST/v2/cover/generate

POST /v2/cover/generate

Generate AI cover images for your music tracks. Consumes 1 credit per request.

POSThttps://udioapi.pro/api/v2/cover/generate

tips

How it works:

  • Step 1: Call /v2/cover/generate with your music task ID to start cover generation
  • Step 2: Use the returned taskId to poll /v2/cover/status for results
  • Step 3: When status is SUCCESS, get the generated cover images from images array

Credit Cost: 1 credit per cover generation request.

Important Notes:

  • Cover image file URLs will be retained for 14 days
  • Each music task can only generate a Cover once; duplicate requests will return a 400 error
  • It's recommended to call this interface after music generation is complete
  • Usually generates 2 different style images for selection
