Company Headcount API FAQs

What is historical headcount data?
Historical headcount data is a time series of employee counts for a company, captured as monthly snapshots. It shows how a company's workforce has grown or contracted over time, including department-level breakdowns for each period.
How can I track company headcount changes?
Use the Company Headcount API to query any company by domain. The API returns the current observed employee count along with monthly historical snapshots, so you can compare headcount across any time period and track changes programmatically.
Can I get employee count by department?
Yes. Every response includes a department_headcount breakdown with counts for engineering_technical, sales, marketing, product_management, finance, human_resources, design, c_suite, legal, and more. Each historical snapshot also includes department data so you can track department-level trends over time.
How can I identify growing companies using employee data?
Compare the observed_employee_count across historical snapshots to calculate growth rates over any period. Rapidly growing headcount is a strong buying signal for sales teams, a health indicator for investors, and a competitive benchmark for market research.
What inputs does the API accept?
You can look up workforce data using the domain parameter. The API returns the observed employee count, employee count range, department-level headcount breakdown, and monthly historical snapshots with full department data.
How much does the Company Headcount API cost?
Pricing is based on our credit system, where each API call has its own credit usage. For the most current and detailed information on credit costs and monthly plans, please visit our pricing page.
Do I get charged if no headcount data is found?
No. You are only charged credits when the API successfully returns headcount data. If the company is not found or no headcount data is available, no credits are deducted.
