## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 webbersites-ai-image-generation-api-213d28a2 -d '<json body>'
```

Example prompt: Generate a photorealistic 16:9 image of a sleek espresso machine on a marble countertop in a sunlit modern kitchen — I want to use it as a product hero shot.

## When to prefer this

Choose this endpoint when you need AI-generated images with strong text rendering, photorealistic scenes, product shots, illustrations, or UI mockups — especially when you also want reference-image-based editing or composition (e.g. 'put this product on this beach'). Prefer it over generic image generators when you need flexible aspect ratios and pay-per-call pricing with no API key setup.

## Known failure modes

- Invalid or missing prompt returns an error response
- Unsupported aspect ratio value returns a validation error
- Payment failure or insufficient funds blocks the request via x402
- Reference image URL is unreachable or malformed returns an error
- Prompt violates content policy and is rejected
- More than 3 reference images provided may cause an error

## How this service works

AI IMAGE GENERATION — POST {prompt} and get back a PNG, base64 in JSON (?raw=1 for raw bytes). Gemini 2.5 Flash Image (nano-banana): photoreal scenes, illustrations, product shots, UI mockups — renders text in images well. Optional {aspect_ratio}: 1:1 (default), 16:9, 9:16, 4:3 + 6 more. Reference images: pass {url} or {image_base64}, or up to 3 in {reference_images}, to edit, restyle, or compose ('put this product on this beach'). The x402 payment IS the auth.

## Output

A JSON object containing the generated image as a base64-encoded PNG string; if ?raw=1 is appended to the request, returns raw PNG bytes directly instead.
