Frequently Asked Questions (FAQ)

Where does this US Public Company B2B data come from?

All company metadata—including legal entity names, corporate headquarters phone numbers, physical street addresses, EIN tax IDs, and SIC industry codes—is extracted directly in real time from official U.S. Securities and Exchange Commission (SEC EDGAR) entity registration files.

Can I use this API inside Clay, n8n, or Make for B2B lead enrichment?

Yes. You can connect this Actor to Clay, n8n, Make, or Zapier using the native Apify integration or HTTP Request node to enrich hundreds of public company tickers at once and push the results straight into HubSpot, Salesforce, or Google Sheets.

What is the difference between CIK and EIN?

The CIK (Central Index Key) is a 10-digit identifier assigned by the SEC to track public filings on EDGAR. The EIN (Employer Identification Number) is the official 9-digit federal tax ID assigned by the IRS to the corporation. This Actor extracts both identifiers automatically.
