Best Image Generation APIs for E-commerce [2026 Guide]

Last Black Friday, I watched a client manually add "30% OFF" badges to 400 product images. It took two days. Two days of copy, paste, export, upload.

This year? They used an image API. Same 400 images, done in 15 minutes.

That's why e-commerce needs image generation APIs. Here's what you can actually do with them.
