Decision Guidance

Use Exa when: You need to connect AI agents or apps to real-time, high-quality web data; your team requires enterprise compliance (SOC 2, zero data retention) and high-capacity search; you're working on recruiting, financial research, code referencing, marketing, or other projects needing vertical-specific search.

Consider alternatives if: You only need basic web search functionality—existing SERP APIs may suffice; you're an individual developer or small project with limited budget—evaluate free or low-cost search APIs first; your research is static and doesn't require real-time data updates.
