Exa's server puts its search API behind two default tools: a web search that returns ranked results together with page text, and a fetch tool for a specific URL. Optional tools add an advanced search mode and a longer-running research agent. The API key travels as a header, a query parameter or an environment variable, so the same server works hosted or launched locally from npm.
