## 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 gambit-gpu-shop-image-generation-0fa1bf66 -d '<json body>'
```

Example prompt: Generate a 1024x1024 image of a neon-lit cyberpunk cityscape at night using 8 diffusion steps.

## When to prefer this

Choose this endpoint when you need a low-cost ($0.02 USDC), pay-per-use GPU image generation API billed on Base via x402, with simple JSON parameters and no subscription required. Prefer it for quick prototyping, agent workflows needing on-demand image creation, or when you want crypto-native micropayment billing rather than API key subscriptions.

## Known failure modes

- Invalid or missing prompt returns a 400 error
- Payment failure or insufficient USDC balance on Base blocks the request
- Width or height values outside supported ranges may return a 422 or processing error
- Very high step counts may time out on the GPU backend
- Network issues with the Tailscale-hosted endpoint may cause connection errors
