## 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 agishub-text-to-image-generator-e480de73 -d '<json body>'
```

Example prompt: Can you generate an image of a serene mountain lake at sunset with golden reflections on the water, using 6 diffusion steps for higher quality?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call AI image generation capability without managing API keys or model infrastructure, especially in agentic workflows where x402 micropayment support is required. It is well-suited for low-volume, on-demand image creation with adjustable quality via diffusion steps.

## Known failure modes

- Empty or missing prompt parameter returns a validation error
- Diffusion steps value outside 1-8 range returns a parameter error
- Very long or complex prompts may produce unexpected or degraded results
- Payment not provided or insufficient USDC balance results in a 402 Payment Required response
- Server-side generation timeout for highly complex prompts

## How this service works

Generate an image from a text prompt (returned base64-encoded PNG).

## Output
