New building permits, the day they're issued. One API call at a time.

Who uses permit data

A permit is a public signal that a property owner is spending money on a project right now, and often needs more than one trade.

What's in the data

Permits issued in the last 30 days, by category. Live from the database. Click a category to explore its trend and busiest cities.

Each record includes the permit number, category, the city's own permit type, description, street address, city, zip, issue date and, where the city publishes them, contractor name, job value and coordinates. Property-owner names are never included.

Pricing

Pay per request in USDC on Base, Solana, Polygon or Arbitrum. No minimums, no keys, no monthly bill. Bad requests are rejected free before any payment.

For AI agents and developers

PermitInfoBroker uses x402, the open HTTP payment standard. Any x402-aware client pays automatically.

1. Call an endpoint. You get 402 Payment Required with the price and where to pay.
2. Your client signs a USDC payment from its wallet and retries the same request.
3. The payment settles on Base, Solana, Polygon or Arbitrum and you get the JSON results. That's it.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { ExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
client.setSpendControls({ maxAmountPerPayment: "$1" });
client.register("eip155:*", new ExactEvmScheme(privateKeyToAccount(process.env.KEY)));
const fetchPaid = wrapFetchWithPayment(fetch, client);

const res = await fetchPaid(
  "/v1/permits/search?jurisdiction=collin-county-tx&category=pool&city=Frisco&since=2026-10-01"
);
console.log(await res.json());
