## 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-v1-5-image-generation-13bc6d91
```

Example prompt: Generate a photorealistic image of a misty mountain lake at sunrise, 512 pixels wide by 512 pixels tall, using 20 diffusion steps for maximum quality.

## When to prefer this

Choose this endpoint when you need a lightweight, no-signup Stable Diffusion v1.5 image generation call paid per-use with USDC on Base, Polygon, Arbitrum, World, or Solana via x402 — ideal for agents that handle crypto wallets and want to avoid API key management.

## Known failure modes

- Insufficient USDC payment or unsupported chain returns HTTP 402 Payment Required
- Invalid or missing prompt returns a 400 error
- num_steps out of range (1-20) returns a validation error
- Width or height values unsupported by the model may be silently clamped or return an error
- Service unavailable or Workers AI backend timeout returns 500

## How this service works

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

## Output
