## 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-fast-image-generation-via-zeroreader-20c950d9 -d '<json body>'
```

Example prompt: Generate an image of a futuristic Tokyo skyline at night with neon lights reflecting on rain-soaked streets — use 4 inference steps and give me the PNG.

## When to prefer this

Choose this endpoint when you need fast (~2s) text-to-image generation for prototyping, quick visual drafts, or any scenario where speed is prioritized over maximum quality. It is ideal when you want a PNG output and can accept slightly lower fidelity than slower diffusion models. Prefer over heavier models when cost ($0.01/call) and latency are key constraints.

## Known failure modes

- Prompt missing — returns 400 bad request
- Steps value exceeds maximum of 8 — returns validation error
- Payment not provided or insufficient — returns 402 Payment Required
- Model overloaded or unavailable — returns 503 Service Unavailable
- Prompt triggers content policy — returns 400 or 403 with policy violation message
