AN ENRICHMENT WORKFLOW
From company domain to qualification context
Pass a website URL to the technology lookup endpoint. Use returned detections in your own application to classify accounts by platform or technology.
Example platforms to detect
Shopify
WordPress
Webflow
Technology lookup endpoint
POST https://api.stackcrawler.com/v1/lookupSupply a website URL and authenticate with your API key. Follow the API documentation for the complete request.
Enrich the domains you already have
Start with a company website
Take the website URL from your own account list. Normalize and validate the URL before sending a lookup request.
Look up the detected stack
Call the technology lookup API using your API key. Consult the documentation for the request fields and response format.
Apply your own qualification rules
Use the detected technologies in your own system to segment accounts or route prospects. Handle missing detections and failed requests explicitly.
You build the connection to your sales tools
This is an API workflow, not a ready-made CRM integration. Your application handles authentication, field mapping, retries, and storage. Technology detection may be incomplete; a missing detection does not prove a tool is absent.
Build around your own qualification rules
- Use website URLs from your own account list
- Validate detections before relying on them
- Choose request allowances for your workflow
Before you integrate
Can I try the API before choosing a plan?
Accounts include 25 free API requests. Pro includes 500 requests per month; see the current pricing and documentation for Advanced allowances and fair-use limits.
Does this discover new company domains?
Technology lookup inspects a URL you provide. To discover sites using a technology, use the separate Websites by Technology API documented on the API overview.
Where do I get an API key?
Sign in and open the API area of your dashboard to manage API keys. Keep keys on your server rather than exposing them in browser code.
