SERP API
A SERP API is a web service that returns search engine results page data — organic positions, URLs and rankings — as structured JSON, so developers can collect SERP data programmatically through code instead of scraping Google by hand.
How a SERP API works
You send an HTTP request describing what you want — a query or a domain, a search engine and usually a date or location — and the API responds with machine-readable JSON instead of an HTML page. Your application parses that JSON to read positions, ranking URLs and related metrics, with no browser, proxies or scraping to maintain.
What it is used for
Typical uses are rank tracking, monitoring how a site moves for a set of keywords, competitor research and feeding SERP data into dashboards or models. Because the data is structured, it slots straight into scripts, spreadsheets and pipelines.
