Features

Everything you need to ship

A single API that handles the complexity of multiple image generation engines so you don't have to.

OpenAI-compatible API

Drop-in replacement for OpenAI's image API. Use the same endpoint structure and SDK you already know — just change the base URL.

Multiple engines

Access Flux Schnell, Flux Dev, Flux Pro, SDXL, SD3, and more through a single unified interface. Switch models with one parameter.

Pay-as-you-go

No monthly minimums. No seat licenses. Pay only for the images you generate — per-image pricing that scales with your usage.

Async & sync modes

Synchronous responses for simple integrations, async polling for high-throughput workloads. Both modes available on every endpoint.

Quick start

Up and running in minutes

Standard HTTP — no SDK required. Works with any language or framework.

curl

curl https://app.artapi.ai/v1/images/generations \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "fal-ai/flux/schnell",
    "prompt": "a beautiful sunset over mountains",
    "n": 1,
    "size": "1024x1024"
  }'

The API follows the OpenAI images endpoint spec. Authenticate with a Bearer token, pass a model name and prompt — get back a URL to your generated image.

Supports all standard parameters: n, size, quality, response_format, and model-specific extensions.
