## 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 gedx402-stable-diffusion-xl-lightning-image-generator-dcefb802
```

Example prompt: Generate a photorealistic image of a golden retriever playing in autumn leaves at 1024x1024 pixels using 20 diffusion steps.

## When to prefer this

Choose this endpoint when you need fast SDXL Lightning image generation without managing API keys, and can pay per-call in USDC on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents that need on-demand image generation in a crypto-native payment context.

## Known failure modes

- Payment failure if USDC balance is insufficient or chain is unsupported
- Invalid prompt returns an error or blank/corrupted image
- Width or height values unsupported by the model return an error
- num_steps outside 1-20 range rejected with validation error
- Network timeout if the model takes too long to generate
- Base64 response may be large for high-resolution outputs

## How this service works

x402 workers ai. pay with usdc on base, polygon, arbitrum, world, or solana. no api keys.
