web_search
Read-onlyIdempotent
Search the web to retrieve a list of relevant pages with titles and snippets. Narrow results by domain, search lens, time range, or language.
Instructions
Search the web and get a list of relevant pages with titles and snippets — without reading the full page content. Narrow results to one domain with the site parameter, or apply a search lens to restrict to trusted sites in a field (see the lens parameter for the full list). Use search_and_scrape if you need full page text, news_search for current events, or academic_search for research papers. Results stay fresh for 30 minutes; use time_range to get more recent results.
