SerpApi
/serpapi
SerpApi turns the entire search landscape into one consistent API, with structured results from Google and 80+ other engines — Bing, Baidu, YouTube, Maps, Scholar, Trends and more. It absorbs the hard parts of scraping search on your behalf: proxies, CAPTCHAs, parsing and constant layout changes, all behind a single stable schema with mature SDKs. Its standout differentiator is legal cover — SerpApi takes on the legal liability of search scraping for its customers — which, with its polished tooling, makes it a trusted default for compliance-conscious teams.
Call SerpApi through the gateway
