Exa

Exa is a neural web search API designed for AI agents and applications. It combines a purpose-built web index with embedding-based retrieval to deliver highly relevant results across categories such as full web, news, companies, research, people, and financials. Exa exposes search, contents, find similar, and answer endpoints, with multiple search modes ranging from fast sub-second responses to deeper multi-step research. It also returns token-efficient highlights and summaries that reduce LLM input costs and supports structured output extraction across more than 70 million indexed companies. Exa is SOC 2 Type II certified, offers Zero Data Retention, and ships Python and JavaScript SDKs.
