Generative AI API Platform | Run FLUX, Kling & Seedance | Muapi

# MuApi.ai > MuApi is a unified AI media generation API platform offering 100+ image, video, audio, and 3D models — Flux, Veo 3, Kling, Seedance, Hunyuan, Runway, GPT-Image, Suno, and more — through a single `x-api-key` HTTP API. Submit-then-poll pattern, transparent per-call credit pricing, no cold starts. Build advanced multimodal workflows visually or programmatically. ## Core API - [API Base](https://api.muapi.ai/api/v1): All model endpoints live under `POST https://api.muapi.ai/api/v1/{model}`. Auth via `x-api-key` header. - [OpenAPI Spec](https://api.muapi.ai/openapi.json): Machine-readable schema for every endpoint. - [API Documentation](https://muapi.ai/docs): Quick-start guides, request/response shapes, and polling pattern. - [Playground](https://muapi.ai/playground): Try every model in the browser with auto-generated forms. - [Pricing](https://muapi.ai/pricing): Per-call credit cost for every model. - [Predictions endpoint](https://api.muapi.ai/api/v1/predictions/{request_id}/result): Poll any submitted job for status (`queued`, `processing`, `completed`, `failed`). ## Category Landing Pages Each category has a dedicated landing page with comparison tables, FAQs, and a category-level llms.txt: - [AI Image Generator](https://muapi.ai/playground/group/text-to-image) · [llms.txt](https://muapi.ai/playground/group/text-to-image/llms.txt) — text-to-image (Flux, Seedream, GPT-Image, HiDream, Qwen, Reve, Midjourney) - [AI Video Generator](https://muapi.ai/playground/group/text-to-video) · [llms.txt](https://muapi.ai/playground/group/text-to-video/llms.txt) — text-to-video (Veo 3, Kling, Seedance, Hunyuan, Runway, Pixverse, Vidu, Hailuo) - [Image-to-Video](https://muapi.ai/playground/group/image-to-video) · [llms.txt](https://muapi.ai/playground/group/image-to-video/llms.txt) — animate any image - [AI Image Editor](https://muapi.ai/playground/group/image-edit) · [llms.txt](https://muapi.ai/playground/group/image-edit/llms.txt) — instruction-b
