## 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 sovereign-engine-image-generation-b387efd4 -d '<json body>'
```

Example prompt: Generate an image of a futuristic cityscape at sunset with flying cars and neon lights.

## When to prefer this

Choose this endpoint when you need lightweight, pay-per-call image generation billed in USDC on Base via x402 micropayments, without a subscription or API key overhead. Particularly useful for agents that need on-demand image synthesis with transparent per-call cost accounting and a self-hosted facilitator setup.

## Known failure modes

- Payment failure – insufficient USDC balance or x402 payment not accepted returns a 402 error
- Invalid or empty prompt – missing or malformed `prompt` field returns a validation error
- Execution timeout – image generation exceeds Cloudflare Worker time limits, returning a timeout error
- Service unavailable – upstream image model unavailable returns a 5xx error
- Rate limiting – too many calls in a short window may result in throttling

## How this service works

Image generation via Cloudflare Workers AI (Flux Schnell).

## Output

Returns a JSON object with a `data` field containing the generated image data, a `success` boolean indicating whether the call succeeded, and a `receipt_id` UUID for the transaction record.
