  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.
