Texas real-estate license CE & renewal check (TREC)

Deterministic TREC rules: continuing-education hours, renewal fees and active-license requirements for Texas real-estate licensees, by license type. Rules-engine output, not an LLM guess.

$0.25 per call — paid in USDC on Base over the x402 protocol, settled by Coinbase. No API key, no signup.

Parameters

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/tx-realestate-ce-check?license_type=sales_agent&first_time="

# 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/tx-realestate-ce-check?license_type=sales_agent&first_time=");
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.
