## 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 merchant-connect-liam-tools-cab8adc6 -d '<json body>'
```

Example prompt: Generate an x402 merchant integration kit for my business 'Pixel Forge Studio' at pixelforgestudio.com — my XRP receiving address is rHb9CJAWyB4rj91VRWn96DkukG4bwdtyTh and I sell one product: 'Pro Icon Pack' (id: pro-icon-pack, $4.50 XRP, delivered at https://pixelforgestudio.com/fulfill/pro-icon-pack) — a bundle of 500 premium SVG icons for designers.

## When to prefer this

Choose this endpoint when you need to generate a ready-made x402 merchant integration kit for a business that accepts XRP and wants to sell digital products with x402-protocol payment gating. Prefer it over manual integration when you have a structured product catalog and want a pre-packaged kit delivered via URL rather than writing x402 flows from scratch.

## Known failure modes

- Missing required product fields (id, name, description, price_xrp, fulfillment_url) returns validation error
- Invalid XRP address format in pay_to causes rejection
- Products array empty or exceeding 20 items fails schema validation
- Invalid URI format for website or fulfillment_url fields
- Payment not completed or underpaid results in 402 response with no kit generated
- Product id not matching pattern ^[a-z0-9-]{1,40}$ causes rejection

## How this service works

Paid generation of an x402 digital-service integration kit. No automatic website installation.

## Output

Returns a JSON object with status 'paid', a unique invoice_id, and a delivery_url pointing to the generated x402 integration kit artifacts — typically hosted artifacts the merchant can download or reference to wire up x402 payment flows on their site.
