## 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-stable-diffusion-v35-large-0e6a8b0a -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need high-quality, detailed text-to-image generation using the SD 3.5 Large MMDiT architecture, especially when FLUX models are not preferred or when Stable Diffusion's specific aesthetic or community ecosystem is desired. SD 3.5 Large is well-suited for complex compositions and photorealistic results at a low per-call cost.

## Known failure modes

- Invalid parameter values (e.g. unsupported resolution or negative steps) — returns 422 validation error
- Model overloaded or service unavailable — returns 503 or timeout
- Insufficient payment — returns payment error
- Empty or missing prompt — returns 422 missing required field
