Parameters

paramdescription
briefevent/offer details (required)
contactemail for delivery (required)

Call it (any x402 client)

# 1. GET without payment → HTTP 402 with PAYMENT-REQUIRED (price, payTo, scheme "exact")
curl -i "https://ai-money-endpoint.nibiashara.workers.dev/shelf/nb-flyer-design?brief=what%20you%20need&contact=you%40example.com"

# 2. Sign the payment (EIP-3009 transferWithAuthorization, gasless) and retry
#    with the PAYMENT-SIGNATURE header → response body is the delivery.

With the official JS client the whole flow is one wrapped fetch:

import { wrapFetchWithPayment } from "@x402/fetch";       // npm i @x402/fetch @x402/evm
const fetchPaid = wrapFetchWithPayment(fetch, { /* your EVM signer */ });
const res = await fetchPaid("https://ai-money-endpoint.nibiashara.workers.dev/shelf/nb-flyer-design?brief=what%20you%20need&contact=you%40example.com");
const data = await res.json();

Or install the MCP server (https://ai-money-endpoint.nibiashara.workers.dev/mcp, registry id biz.nibiashara/shelves) and use the job-named tool for this shelf, or buy_shelf as an escape hatch.
