Exa Just Removed /research and Started Silently Ignoring Two Date Filters — Your Agent Is Probably Pulling Stale Pages R

On May 1, 2026 — today — Exa finished a three-step API deprecation that's been quietly half-breaking AI agents for the past two weeks. The hard cutoff today is the visible piece. The interesting part is what's been broken since April 15 with no error. Three things changed: /research/v1 — sunset today. Calls now fail. Migration: /search with type: "deep-reasoning" . startCrawlDate / endCrawlDate — silently ignored since April 15. Requests still return 200 . The filters just don't apply. resolvedS
