Look Up Any Company's Tech Stack with a Single API Call

Why Company Tech Stacks Matter

Knowing what tools a company uses is gold for B2B sales teams, recruiters, and competitive analysts. If a prospect runs React and AWS, you can tailor your pitch. If a competitor just adopted a new CI tool, that tells you something about their roadmap.

The problem? Gathering this data manually is tedious. StackShare profiles exist, but there's no clean way to pull that information programmatically — until now.

Introducing the StackShare Tech Stack API

The StackShare Tech Stack API gives you structured tech stack data for any company in a single GET request. Pass a company name, get back the tools they use — organized by category (languages, frameworks, DevOps, etc.).

This is useful for:

• Sales enrichment — qualify leads based on their tech choices
• Competitive intelligence — track what tools competitors adopt
• Market research — analyze technology trends across industries
• Recruiting — understand a company's stack before outreach

Quick Example

Here's how to fetch Airbnb's tech stack using fetch():

const response = await fetch(
  'https://api-production-83b0.up.railway.app/api/stackshare-tech-stack-api/company/stack?companyName=airbnb',
  {
    method: 'GET',
    headers: {
      'X-RapidAPI-Key': 'YOUR_RAPIDAPI_KEY',
      'X-RapidAPI-Host': 'stackshare-tech-stack-api.p.rapidapi.com'
    }
  }
);

const data = await response.json();
console.log(data);

The response gives you a structured breakdown of every tool in the company's stack, along with category labels so you can filter by what matters to your use case.

Real-World Use Case: Lead Scoring

Say you sell a Kubernetes monitoring tool. You could hit this API for each company in your pipeline and automatically flag leads that already run Kubernetes. No manual research, no guesswork — just data.

const stack = data.tools || [];
const usesK8s = stack.some(tool =>
  tool.name.toLowerCase().includes('kubernetes')
);

if (usesK8s) {
  console.log('High-priority lead — already on Kubernetes');
}

That's a pipeline filter you can build in an afternoon.
