What is the FLUX API?

FLUX.1 is a family of image generation and editing endpoints from Black Forest Labs. Muapi groups Dev and Schnell with Krea, PuLID, Redux, and LoRA workflows.

Use FLUX Dev for general prompt-to-image quality, Schnell for fast iteration, and editing or LoRA endpoints when a reference or custom style should guide the output. FLUX.2 has a separate hub.

FLUX API capabilities

FLUX.1 generation

Generate images with Dev, Schnell, and Krea variants.

Reference editing

Use PuLID and Redux workflows to guide image creation.

LoRA training

Train custom FLUX style or concept LoRAs.

LoRA inference

Apply a custom FLUX LoRA while generating or editing.

Quick start — FLUX API

curl -X POST https://api.muapi.ai/api/v1/flux-dev \
  -H "x-api-key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"prompt":"A surreal botanical illustration with precise ink details","image_size":"square_hd"}'

# Response: {"request_id":"REQUEST_ID"}
