## 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 flux-1-schnell-image-generator-6fa7011e -d '<json body>'
```

Example prompt: Generate a square 1024x1024 image of a misty mountain forest at sunrise — keep it atmospheric and painterly.

## When to prefer this

Prefer this endpoint when you need fast, low-cost image generation and quality does not need to be photorealistic or highly detailed. It is ideal for rapid prototyping, concept drafts, content pipelines where speed matters, or when budget is constrained. For higher fidelity or accurate text-in-image rendering, prefer FLUX.2 dev instead.

## Known failure modes

- Prompt too short or empty — rejected with validation error
- Prompt exceeds 2000 character limit — truncation or rejection
- Invalid size enum value — request rejected with schema error
- Model may produce low-quality results for highly detailed or complex prompts due to the fast 4-step process
- Network timeout or server-side inference failure — retry recommended

## How this service works

FLUX.1 schnell — The quick classic. Four steps, half a cent.

## Output

A generated image corresponding to the text prompt, in the requested dimensions (1024x1024, 1280x768, or 768x1280). The output is produced via a 4-step diffusion process, optimized for speed at a cost of approximately half a cent per call.
