What is the best API/model to merge two input images into a themed single output image?
00:44 20 Nov 2025

I’m working on a web application where:

  • The user uploads two images.

  • The system merges those images into a single themed output image (for example: wedding theme, birthday theme, festival theme, etc.).

  • The final result should contain both original images placed inside the selected theme background/frame.

I want to know:

  1. Which API or AI model is best suited for this image-merging task?

    • Preferably something that supports adding frames, backgrounds, or templates.

    • Should allow good quality output.

  2. Is there any pricing information per image for those APIs/models?

    • Example: credits per image, or cost per call.

I’ve checked some image-editing and generative-AI platforms but I’m not sure which one is the most suitable for this specific task.

What would be the recommended API/model for this use case?
Any suggestions or pricing guidance would be appreciated.
