Code samples
curl -X POST https://api.cleanlist.ai/v1/enrich/technographic \
-H "Authorization: Bearer $CLEANLIST_API_KEY" \
-H "Content-Type: application/json" \
-d '{"email": "jane@acme.com"}'import Cleanlist from "cleanlist";
const client = new Cleanlist(process.env.CLEANLIST_API_KEY);
const result = await client.enrich.technographic({
email: "jane@acme.com",
});
console.log(result.technographic.title);from cleanlist import Cleanlist
client = Cleanlist(api_key=os.environ["CLEANLIST_API_KEY"])
result = client.enrich.technographic(email="jane@acme.com")
print(result["technographic"]["title"])Common use cases
Find companies using a competitor's product (e.g., all companies using Apollo for sales engagement) and target them with displacement messaging highlighting where you are stronger.
Identify companies using tools that integrate with your product (e.g., companies using Salesforce + Outreach) and position your solution as the missing piece in their existing stack.
Monitor target accounts for new technology adoptions. When a prospect adds HubSpot, trigger an outreach sequence about your HubSpot integration before competitors reach them.
Count how many companies in your target market use a specific technology to estimate total addressable market for a product or feature.

FAQ
How does Cleanlist detect technologies on a domain?
Cleanlist combines multiple detection methods: website HTML scanning (script tags, meta tags, DNS records), job posting analysis (technologies mentioned in engineering job descriptions), and third-party technology databases. Results from multiple sources are cross-referenced to produce a confidence score for each detection.
How many technology categories does Cleanlist track?
Cleanlist tracks technologies across 200+ categories including CRM, marketing automation, analytics, cloud infrastructure, content management, e-commerce platforms, payment processors, monitoring tools, development frameworks, and more. The full category taxonomy is available in the API documentation.
Can I track when a company adds or removes a technology?
Yes. The first_detected field shows when each technology was first observed. By calling the endpoint periodically (weekly or monthly), you can diff the results to detect newly added or removed technologies. The Cleanlist dashboard also supports technology change alerts for monitored accounts.
What is the accuracy of technographic detection?
Detection accuracy varies by technology type. Client-side technologies (analytics, chat widgets, tag managers) are detected with 95%+ accuracy because they leave visible traces in website HTML. Server-side technologies (databases, cloud infrastructure) are detected with 75-85% accuracy through DNS records, job postings, and partnership data. The confidence score on each detection reflects this variation.
