Google Scholar

Search for academic papers, articles, and research results in JSON format.

Endpoint

GET /v1/scholar/{query}

Description

The Scholar Search endpoint allows you to search for academic papers, articles, and research across the scholarly literature. The query parameter should be a URL-encoded query string that follows Google's search parameter format — q= for the search terms, plus optional num= (results per page, up to 200) and start= (result offset for pagination).

Scholar results are drawn from a global scholarly index and are not geo-differentiated, so the X-Proxy-Location and X-User-Agent headers below are accepted but do not change the results.

Authentication

All requests require authentication using the X-Api-Key header. See the Authentication guide for more details.
