## 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 stability-ai-generate-core-cbcf4d89 -d '<json body>'
```

Example prompt: Generate a photographic-style image of a misty mountain lake at dawn with pine trees reflected in the water, in 16:9 aspect ratio as a JPEG, and exclude any people or buildings.

## When to prefer this

Choose this endpoint when you need fast, high-quality text-to-image generation from Stability AI's core model with style preset control. Prefer over Generate SD3 when you want the standard core model rather than Stable Diffusion 3. Use when you need flexible aspect ratios and style presets like photographic or digital-art without the complexity of structure or sketch conditioning.

## Known failure modes

- Invalid or missing prompt returns a 400 error
- Unsupported aspect_ratio value returns a validation error
- Unsupported style_preset string may be rejected or ignored
- Output format value outside jpeg/png/webp causes a validation error
- Prompt triggers content policy filter, returning a 403 or moderation error
- Seed value out of valid range may cause unexpected behavior
- Network timeout on large image generation

## How this service works

Stable Image Core — fast, high-quality text-to-image generation.

## Output

Returns a binary image file (JPEG, PNG, or WebP) of the AI-generated scene based on the provided prompt, conforming to the requested aspect ratio and style preset. The response payload is the raw image data, typically several hundred kilobytes in size.

 "prompt": "A serene landscape with rolling green hills and a clear blue sky at sunset",
