Overview

Exa is a search API designed for AI applications and research workflows. It retrieves relevant pages using semantic search and exposes content that developers can pass into an agent, retrieval system, or analysis pipeline.

The product is aimed at developers and research teams that need programmable discovery rather than a standalone search interface. Query behavior, indexing, and pricing are API-account dependent.
