## 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 onchainexpat-x402-uncensored-ultra-image-generator-1acba58e -d '<json body>'
```

Example prompt: Generate a photorealistic 1536x1024 image of a misty mountain lake at sunrise with pine trees reflected in the water, using the gpt-image-2 model.

## When to prefer this

Choose this endpoint when you need pay-per-request image generation without a subscription, want access to multiple flagship models including Recraft-V4-Pro, or require uncensored image generation with no content policy restrictions and are willing to pay $0.45 USDC per image via the x402 micropayment protocol.

## Known failure modes

- Invalid model ID returns an error — must use gpt-image-2, nano-banana-pro, or recraft-v4-pro
- Invalid width/height combination (e.g. 1536x1536) returns an error — only 1024x1024, 1536x1024, 1024x1536 are valid
- Payment failure via x402 protocol blocks request execution
- Empty or missing prompt returns an error or low-quality result
- Server-side model timeout or rate limit may cause transient failures
