## 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 api-imgzen-dev-a55d198a -d '<json body>'
```

Example prompt: Generate a vivid, high-quality square PNG image of a futuristic cityscape at night with neon reflections on wet streets — use GPT Image 1 with a transparent background.

## When to prefer this

Choose this endpoint when you need OpenAI GPT Image 1 quality specifically, want fine-grained control over style (vivid vs natural), background transparency, aspect ratio, and output format, and are comfortable paying $0.10/image via x402 USDC. Prefer over sibling Gemini endpoints when OpenAI's rendering style is desired. Use over GPT Image 1.5 when the latest OpenAI model is not required and cost parity is acceptable.

## Known failure modes

- Invalid or missing prompt returns an error status
- Reference image URL is unreachable or malformed — generation fails
- More than 5 reference images provided — schema validation error
- Unsupported enum value for style, quality, background, aspect_ratio, or output_format — validation error
- Payment failure via x402 protocol — request not processed
- Server-side model error or timeout — status error with no output URL

## How this service works

imgzen — GPT Image 1, OpenAI high quality — $0.100/image
