## 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 run402-8e3000f7 -d '<json body>'
```

Example prompt: Generate an image of a golden retriever puppy playing in autumn leaves in a sunny park, and give me the PNG back.

## When to prefer this

Choose this endpoint when you need to programmatically generate an image from a text prompt and receive the result as a base64 PNG, especially in agentic workflows that support x402 micropayments. At $0.03 USDC per call it is cost-effective for single image generation tasks without a subscription.

## Known failure modes

- Invalid or empty prompt returns an error
- Content policy violation if prompt contains disallowed content
- Payment failure if USDC balance is insufficient (x402 payment required)
- Timeout if image generation takes too long
- Malformed request body returns 400 error

## How this service works

Generate an image from a text prompt using AI. Returns base64 PNG.

## Output

A base64-encoded PNG image file that the agent can decode and display, save, or pass to downstream processing steps.
