What is an AI image API?
An AI image API lets developers generate or edit images from their own app over HTTP — text-to-image, image-to-image, inpainting, upscaling, or background removal — without running models on their own hardware. You send a prompt or image and get back a generated image.
Core features to look for
- Text-to-image and image-to-image endpoints
- Inpainting, outpainting, and background removal
- Upscaling and enhancement APIs
- Model choice (SD, FLUX, and other hosted models)
- Async jobs, webhooks, and batch generation
- Usage-based pricing, SDKs, and free credits
Who uses AI image APIs, and how
In-app generation
Add text-to-image or avatars to your product without hosting models.
Editing pipelines
Automate background removal, upscaling, and inpainting at scale.
Batch & automation
Generate product shots or variations in bulk via async jobs.
Cost & model choice
Compare per-image pricing, models, and free credits for apps.
How does an AI image API work?
An AI image API hosts diffusion and vision models on the provider's servers and exposes them over HTTP. You send a prompt or source image with your API key; the model runs remotely — often as an async job you poll or get a webhook for — and returns an image, billed per image or per compute second.
