Exa

Exa is an AI search API built for developers who need high-quality web context inside AI applications. It provides search, content retrieval, deep research, monitoring, and enrichment capabilities that help agents and chatbots access current information from the web. Unlike a general consumer search engine, Exa is designed as infrastructure for AI products. Developers can use it to ground model responses, retrieve relevant documentation, search company or people data, power research agents, monitor the web for changes, and feed clean context into LLM workflows. The platform is especially useful for SaaS founders building coding agents, AI research tools, sales intelligence products, support assistants, market monitoring systems, and RAG pipelines that need live web data. Exa also offers endpoint-level pricing for search, contents, deep search, monitors, and agent runs, making it flexible for different product designs. For FutureStack, Exa is a tier-one developer tool because web search is becoming a core primitive for AI agents. It helps builders add real-time knowledge and retrieval to their products without building a search engine, crawler, and ranking system from scratch.
