Company Intelligence API API — Free to Use

#api #webdev #javascript #productivity

Getting Complete Company Intelligence from a Single API Call

When you need comprehensive company data, juggling multiple APIs is painful. The Company Intelligence API consolidates everything—LinkedIn profiles, funding info, tech stacks, and employee counts—into one clean response.

What It Does

This API enriches domain names with actionable intelligence:

  • LinkedIn company pages - Direct links and verified data
  • Crunchbase funding - Investment rounds and amounts
  • Tech stack - Technologies powering the site (via BuiltWith)
  • Contact information - Email, phone, and address data
  • Employee count - Current headcount from verified sources

Perfect for lead generation, market research, competitor analysis, or B2B sales automation.

How to Use It

The main endpoint is straightforward. You pass a domain and specify what data you want included:

const domain = 'github.com';
const apiKey = 'YOUR_RAPIDAPI_KEY';

fetch('https://company-intelligence-hub-api-production.up.railway.app/api/company/enrich?domain=' + domain + '&include_funding=true&include_tech=true', {
  method: 'GET',
  headers: {
    'x-rapidapi-key': apiKey,
    'x-rapidapi-host': 'company-intelligence-hub-api.p.rapidapi.com'
  }
})
.then(response => response.json())
.then(data => {
  console.log('Company Name:', data.company_name);
  console.log('Employee Count:', data.employee_count);
  console.log('LinkedIn:', data.linkedin_url);
  console.log('Tech Stack:', data.technologies);
  console.log('Funding:', data.funding);
  console.log('Email:', data.contact_email);
})
.catch(error => console.error('Error:', error));
