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 gedx402-stable-diffusion-v1-5-inpainting-image-generator-96cac6db
```

Example prompt: Generate an image of a cozy mountain cabin at sunset with snow-covered pine trees, 512 pixels wide by 512 pixels tall, using 20 diffusion steps for maximum quality.

## When to prefer this

Choose this endpoint when you need AI image generation via Stable Diffusion v1.5 Inpainting and want to pay per-call with USDC cryptocurrency without managing API keys or subscriptions. Ideal for agents operating in crypto-native environments supporting x402 micropayments on Base, Polygon, Arbitrum, World, or Solana. Prefer this over traditional API-key-based services when building permissionless, key-free pipelines.

## Known failure modes

- Payment failure if USDC balance is insufficient or x402 payment is not accepted
- Invalid prompt resulting in poor or unexpected image output
- Width or height values unsupported by the model causing a 400 error
- num_steps outside the 1-20 range causing a validation error
- Network timeout if diffusion inference takes too long
- Malformed base64 response if the model backend encounters an internal error

## How this service works

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

## Output

A JSON object containing a single 'image' field with the generated image encoded as a base64 string, which can be decoded and saved as a PNG or JPEG file.
