Build a Professional License Verification System in Node.js

Background checks, hiring, and contractor vetting all require license verification. Here's the fastest way:

The Problem

License verification is fragmented across 50 state licensing boards, each with its own website, search interface, and data format. If you're building:

  • A hiring platform that verifies nurses, contractors, or real estate agents
  • A compliance system for a staffing agency
  • A background check pipeline for lending decisions

...you're looking at maintaining scrapers for dozens of state board websites. Each one breaks when the state updates their site. It's a nightmare.

The Solution: License Verify API

The License Verify API aggregates license verification across multiple states (FL, CA, NY, TX, and more) into a single REST endpoint. One request, structured JSON back.

Here's a Node.js integration that verifies a professional license:

const axios = require("axios");

const API_URL = "https://license-verify-api.p" + "rapidapi.com/api/verify";
const headers = {
  "x-rapidapi-key": "YOUR_RAPIDAPI_KEY",
  "x-rapidapi-host": "license-verify-api.p.rapidapi.com"
};

async function verifyLicense(licenseNumber, state, licenseType) {
  const response = await axios.get(API_URL, {
    headers,
    params: {
      license_number: licenseNumber,
      state: state,
      license_type: licenseType
    }
  });

  const result = response.data;
  console.log(`Name: ${result.licensee_name}`);
  console.log(`Status: ${result.status}`);
  console.log(`Expires: ${result.expiration_date}`);
  console.log(`Disciplinary actions: ${result.disciplinary_actions.length}`);
  return result;
}

// Verify a Florida contractor license
verifyLicense("CBC1234567", "FL", "contractor");

Example Response 

{
  "licensee_name": "SMITH CONSTRUCTION LLC",
  "license_number": "CBC1234567",
  "license_type": "Certified Building Contractor",
  "state": "FL",
  "status": "Active",
  "issue_date": "2019-06-15",
  "expiration_date": "2027-08-31",
  "disciplinary_actions": [],
  "board": "Florida DBPR"
}
Enter fullscreen mode Exit fullscreen mode

Use Cases

HR and recruiting platforms — Automate license verification during onboarding. Instead of asking candidates to upload PDFs (which can be faked), verify directly against the source of truth.

Contractor marketplaces — Verify that every contractor on your platform has a valid, active license before they can bid on jobs. Run nightly checks to catch expirations.

Lending and insurance — Underwriting decisions for contractors and professionals need license status. Automate what used to be a manual lookup.

Healthcare compliance — Verify nursing licenses across states for travel nurse staffing. The API handles the state-by-state fragmentation so you don't have to.

Getting Started

The free tier includes 50 verifications/month. Each request hits the actual state licensing board in real-time, so you're always getting current data — not a stale database copy.
