How to Use Flux.1 Schnell API in 5 Lines of Python (Free Tier Available)

Flux.1 Schnell is the fastest open-source text-to-image model from Black Forest Labs — Apache 2.0 licensed, 12B parameters, generates images in 1–4 steps. Here's how to call it via NexaAPI (cheapest inference API, 56+ models, free tier): 5-Line Python Example import requests response = requests . post ( " https://flux-schnell2.p.rapidapi.com/generate " , headers = { " x-rapidapi-key " : " YOUR_KEY " , " x-rapidapi-host " : " flux-schnell2.p.rapidapi.com " }, json = { " prompt " : " A neon-lit Tokyo street at night, cinematic " , " num_inference_steps " : 4 } ) print ( response . json ()[ " image_url " ]) That's it. One API call, one image URL back. Why NexaAPI for Flux.1 Schnell? Provider Price/Image NexaAPI $0.001 ← cheapest FAL.ai $0.003 Replicate ~$0.003 3× cheaper than FAL.ai. Plus you get 55 other models (SDXL, Flux Dev, Flux Pro, vision models, TTS) under the same API key.
