Caveats

• ⚠Requires an Exa API key (obtain from dashboard.exa.ai/api-keys) unless using OAuth login
• ⚠Advanced-search category filters have restrictions: includeText/excludeText only support single-item arrays (multi-item causes 400); company/people categories reject certain date/domain filters
• ⚠Auth-required LinkedIn content cannot be retrieved; agents should fall back to browser
