Web search API for AI agents, an Exa / Tavily alternative that costs less than both: Google-quality results re-ranked for authority (primary sources first), merged with papers (arXiv, Semantic Scholar), GitHub and news when the query needs them. Category (news, research paper, github, financial, company, pdf, docs), include/exclude domains, country, language, city, freshness, private mode. Each result: domain authority rank and type. ~1.7 s.
