Search the web and return structured results. Output: {"query":str,"queryRewritten":str?,"queryYear":int?,"engine":str,"engineSwitched":bool,"cached":bool, "total":int,"deduped":int,"freshnessApplied":bool,"freshnessAutoInferred":bool?, "results":[{"id":str,"title":str,"url":str,"snippet":str,"domain":str}]} Use the "id" of a result with fetch_page to deep-read a page.

Fetch a page and return its content as structured Markdown. Pass either "url" or the "id" returned by search/research (id looks up the already-seen URL). extractMode "summary" returns de-noised mainText (saves tokens); "full" returns the full page Markdown. Output: {"url":str,"title":str,"description":str,"headings":[{level:int,text:str}], "mainText":str,"markdown":str,"length":int,"truncated":bool,"cached":bool}

One-call research: search + fetch the top pages and return an evidence brief. Use this instead of chaining search/fetch_page yourself. Pages are selected for domain diversity (top hit per domain, then by rank) so one anti-bot 403 site can't sink the brief. Output: {"query":str,"engine":str,"cached":bool, "overview":{"total":int,"results":[{"id":str,"title":str,"url":str,"snippet":str,"domain":str}]}, "pages":[{"id":str,"url":str,"rank":int,"title":str,"headings":[{level:int,text:str}],"content":str,"length":int,"truncated":bool}|{"url":str,"rank":int,"error":str}]} Base your answer on the pages' content and cite their URLs.
