## 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 gpt-image-2-via-xona-agent-medium-quality-76c7ffb6 -d '<json body>'
```

Example prompt: Generate a photorealistic square image of a cozy coffee shop interior at golden hour, warm lighting, with a chalkboard sign that reads 'Morning Brew' above the counter — use GPT Image 2 at medium quality.

## When to prefer this

Choose this endpoint when you need high-quality photorealistic images with accurate text rendering and strong prompt-following, especially when using OpenAI's GPT Image 2 model is a priority. It is well-suited for marketing visuals, product mockups, editorial images, or any use case requiring legible in-image text. Prefer this over lower-fidelity models when detail and instruction-following matter. If you need higher quality or more reference images, consider the sibling max-quality endpoint. This endpoint is cost-effective at $0.12 USDC per image.

## Known failure modes

- Prompt too vague or ambiguous — output may not match intent
- Reference image URLs are inaccessible or malformed — endpoint returns an error or ignores them
- Content policy violation in prompt — request rejected by OpenAI safety filters
- Only 1:1 aspect ratio is supported — other ratios will be ignored or cause errors
- Network timeout or Replicate backend latency under heavy load
- Payment failure via x402 — request not processed if USDC balance is insufficient

## How this service works

AI image generation using GPT Image 2 (OpenAI via Replicate). High-quality photorealism with sharp text rendering and strong instruction following. Quality: medium.

## Output

A generated image file (URL or binary) depicting the scene described in the prompt. The image is square (1:1 aspect ratio), rendered at medium quality using OpenAI's GPT Image 2 model, with strong photorealism, sharp in-image text rendering, and close adherence to the input prompt. If reference images were provided, they influence the output style or content.
