Exa

What it does

Exa is a search API that retrieves by meaning rather than keywords, plus a readable web interface on top. It is the tool teams reach for when building an agent that has to find comparable suppliers, similar products or recent funding news at scale.

It is developer-first: the value shows up in an integration, not in a browser tab. Free credits cover evaluation; production use is metered.

Standout features

• Semantic, meaning-based web search
• Clean API for agent and RAG pipelines
• Contents endpoint returns full page text
• Company and research-paper indexes
• Web interface for ad-hoc research
