## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability fal-ai-v1-1-2efacc63 -d '<json body>'
```

Example prompt: Generate a photorealistic image of a serene mountain lake at golden hour with snow-capped peaks reflected in the water — use 1024x768 resolution, guidance scale 7.5, and seed 42 so I can reproduce it later.

## When to prefer this

Choose FLUX1.1 [pro] when you need professional-grade image quality at a balance of speed and fidelity for resolutions up to ~1024x1024. Prefer this over FLUX1.1 [pro] ultra when you don't need 2K resolution and want lower cost ($0.035 vs higher). Prefer over FLUX.1 [dev] when you need commercial-grade output. Prefer over Stable Diffusion 3.5 Large when you want FLUX's distinct aesthetic and prompt adherence.

## Known failure modes

- Invalid image dimensions (unsupported width/height values) — returns 400 error
- Prompt too long or containing disallowed content — returns 422 or content policy rejection
- Payment failure (insufficient USDC balance) — transaction not processed, request rejected
- Model timeout on complex prompts — returns 504 or partial response
- Invalid guidance_scale value out of supported range — returns 400 validation error
