## 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-7552fc31
```

Example prompt: Generate a photorealistic image of a misty mountain lake at sunrise with pine trees in the foreground — make it 1024x768 pixels, use 20 diffusion steps for best quality.

## When to prefer this

Choose this endpoint when you need a fast, no-signup image generation capability paid per-call with USDC on supported blockchains (Base, Polygon, Arbitrum, World, Solana). Ideal for agents that lack traditional API key management but can execute on-chain micropayments. Best for single image generation from a text prompt with SDXL Lightning quality.

## Known failure modes

- Payment not received or insufficient USDC balance — 402 Payment Required response
- Invalid prompt or missing required field — 400 Bad Request
- num_steps out of range (must be 1–20) — validation error
- Unsupported width/height combination for the model — generation failure or distorted output
- Network timeout if diffusion steps are high and worker times out
- Unsupported blockchain network provided for payment
