Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 stable-diffusion-v1-5-inpainting-image-generation-via-x402-32b4e688
```

Example prompt: Generate an image of a serene mountain lake at sunrise with pine trees reflecting in the water — make it 512x512 pixels with 20 diffusion steps for best quality.

## When to prefer this

Prefer this endpoint when you need on-demand stable diffusion image generation without API key registration, especially when paying with USDC on Base, Polygon, Arbitrum, World, or Solana. Ideal for agents operating in crypto-native environments using the x402 payment protocol. Best for inpainting-style generation tasks using the v1.5 model.

## Known failure modes

- Payment not received or insufficient USDC balance — returns HTTP 402 requiring payment
- Invalid prompt or missing required fields — returns 400 bad request
- num_steps out of range (must be 1-20) — validation error
- Unsupported blockchain network for payment — payment rejected
- Model inference timeout on Cloudflare Workers — returns 500 or timeout error
- Malformed base64 in response if model fails internally

## How this service works

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

## Output

Returns a JSON object containing a base64-encoded string of the generated image, which can be decoded into a PNG or JPEG image file.
