Apiframe is a single AI image generator API that gives you text-to-image, image editing and reference-image generation across every major model. Swap models with one parameter, ship faster, and pay only for successful generations - no separate provider accounts required.

What you can build

Text-to-image

Turn prompts into high-resolution images with state-of-the-art models like Flux 2 and Imagen 4.

Image editing & inpainting

Edit, fill and restyle images with Nano Banana and Flux Fill - prompt-driven, no masks required.

Reference & character consistency

Keep characters and styles consistent across generations with Ideogram Character and reference images.

Upscaling & cleanup

Upscale and sharpen outputs with Topaz and Clarity, or remove backgrounds in one call.

AI image models on one API

Call any of these image models with the same request shape. Pick a model to see its API reference, parameters and code samples.

Frequently asked questions

What is the best AI image generator API?

It depends on your use case. Apiframe gives you every leading image model - Flux, Midjourney, Nano Banana, Seedream, Ideogram, GPT Image and Imagen - behind one API, so you can benchmark them and pick the best per task without integrating each provider separately.

Can I generate images from text with the API?

Yes. Send a POST request with a model id and a text prompt to generate images. The same endpoint supports image editing and reference-image generation depending on the model.

How much does the AI image generation API cost?

Pricing is pay-as-you-go - you only pay for successful generations. See the pricing page for plans and volume discounts.

Which image models are available?

Flux, Midjourney, Nano Banana, Seedream, Ideogram, GPT Image, DALL-E, Imagen, Qwen Image, Reve, Grok Image 2, plus upscaling and background-removal utilities - all through one API.
