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.

Technical details
Endpoint
POSThttps://liam-tools-merchant-connect.evangrant69420.workers.dev/v1/merchant-connect?utm_source=zero.xyzWhen to prefer
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.
