## 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 alfred-x402-image-generation-193dd408 -d '<json body>'
```

Example prompt: Generate a high-quality image of a futuristic city skyline at sunset — use schnell quality mode.

## When to prefer this

Choose this endpoint when you need text-to-image generation via a self-hosted, pay-per-use x402/Lightning micropayment API — especially when you want per-call pricing at $2.10 USDC with no subscription required and results cached by payment hash. Prefer this over hosted SaaS image generators when operating in a Lightning/x402 payment context or when the requester specifically wants ALFRED's self-hosted toolset.

## Known failure modes

- HTTP 402 returned if no valid Lightning payment has been made — client must pay the invoice in the response body and retry with X-Payment-Hash header
- Invalid or expired payment hash results in re-issuance of invoice
- Unsupported quality value may produce an error or fall back to default
- Prompt too long or empty may result in a 400 Bad Request
- Self-hosted service may have downtime or rate limits not publicly documented

## How this service works

Self-hosted personal-assistant paid tools via Lightning. Uses x402-shaped protocol (L402 lineage): HTTP 402 with a Lightning invoice in the response body + WWW-Authenticate header, retry with X-Payment-Hash: <hex> once paid. Results cached per payment_hash so legitimate retries don't cost twice.

## Output

Returns a generated image (exact format unspecified in schema; likely an image URL, base64 data, or binary blob) keyed to the payment hash. Results are cached per payment hash so retrying the same paid request does not incur a second charge.
