Exa

Exa's API has expanded from a single search endpoint into a set of specialized retrieval products — Company Search, People Search (1B+ profiles), Instant Search, and Monitors — with markdown content and auto-routing now defaults. The recent headline is Exa Agent, a class of web-research agents accessible via API, marking a shift from returning results to running research.

The arc is clear: from raw search, to entity-specific verticals, to agentic research that composes those primitives. Defaults have steadily moved toward developer ergonomics (markdown, auto search, contents-by-default), while older parameters and a legacy /research endpoint are being deprecated as the surface consolidates.
