How do APIs work, and who’s using them?

Think of an API, or Application Programming Interface, as a bridge that allows two systems to “talk” to each other. For example, when you request weather data, the app doesn’t have its own weather station—it sends a request to an external service, and the API handles this exchange of information.

But APIs aren’t just for developers. Similarweb’s APIs make it easy for business users, digital marketers, sales teams, and analysts to access actionable data at scale. No need to manually scrape data from websites or use complex tools—APIs automate the process, delivering fresh, relevant insights directly into your workflows.

Why are APIs essential for your business?

APIs empower businesses to automate data gathering, streamline processes, and integrate valuable data into existing tools. For digital marketers, business intelligence teams, and sales professionals, this means more time for strategy and analysis and less time spent on manual data extraction.

More importantly, Similarweb’s APIs provide direct access to data on web traffic, keyword performance, app usage, and competitor analysis, giving your business the edge it needs to stay ahead. Imagine integrating Similarweb’s traffic insights or keyword data directly into your reports, dashboards, or CRM — no middlemen, no extra steps.
