AI Image Generator
MuApi gives you a single HTTP endpoint to call every leading text-to-image model in production. Submit a prompt, get back a request ID, poll for the result. No model-specific SDKs, no cold starts, no surprise billing — every model is priced per call in transparent credits, and you only pay for successful generations. Mix and match Flux Schnell for fast iteration, Seedream and HiDream for photoreal output, GPT-Image and Reve for text rendering, or Midjourney and Qwen for stylized art — all via the same `x-api-key` header and JSON body shape.

Frequently Asked Questions
Which AI image generator API is the best?
It depends on the trade-off you want. Flux Schnell and Seedream lead on photoreal speed; HiDream and Reve produce the most accurate in-image text; Midjourney and Qwen Image lead on stylized artistic output; GPT-Image is the strongest generalist with editing support. MuApi exposes all of them so you can A/B in code without rewriting your client.
How do I authenticate?
Send your MuApi key as the `x-api-key` header on every request. Create one at https://muapi.ai/access-keys.
What does a request look like?
POST a JSON body to `https://api.muapi.ai/api/v1/{model}` (e.g. `flux-schnell`). You get back a `request_id`. Poll `GET /api/v1/predictions/{request_id}/result` until `status` is `completed`, then read the image URLs from `outputs[]`.
Is there a free tier?
Yes — new accounts get free credits to try every model in the playground before committing.
How is pricing calculated?
Each model has a per-call cost in credits, listed on the playground page. Some models (e.g. variable-resolution or duration-based ones) compute cost dynamically from the request payload — the playground shows the live calculation as you tweak inputs.
Can I use this from an agent or LLM?
Yes. MuApi ships an MCP server (`muapi mcp serve`) that exposes every model as a tool — drop it into Claude Code, Cursor, or any MCP-aware agent and call image generation by name.
