## 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 agent402-tools-premium-image-generation-46cc640c -d '<json body>'
```

Example prompt: Generate a premium 1024x1024 image of a lone astronaut standing on a red Mars landscape at sunset, with Earth visible in the sky and dramatic orange lighting — use GPT Image 2 for maximum detail.

## When to prefer this

Choose this endpoint when you need a high-detail, coherent AI-generated image using GPT Image 2 without managing your own API key, and are willing to pay $0.30 USDC per call via x402. Prefer this over standard/economy alternatives when image quality and detail are priorities. It is ideal for agents that need on-demand image generation with crypto-native pay-per-call billing.

## Known failure modes

- Prompt exceeds 4000 characters — request rejected with validation error
- Payment via x402 fails or is insufficient — request blocked
- Model unavailable or overloaded — server error returned
- Prompt contains disallowed content — content policy rejection
- Network timeout during image generation — no image returned
