Exa

Exa positions itself as a data layer for AI agents rather than a traditional search engine. Its core offering is a search API that retrieves real-time information from the public web alongside private data sources, so agents can ground responses in current, verifiable content instead of stale training data.

The product line includes a Search API, Contents API, Agent API, and Monitors API, plus an Exa Library and integrations such as Exa Connect. Developers can choose latency profiles like Lite at around 450ms, Auto at about one second, and Deep at roughly ten seconds, and can request results, answers, or structured output from the same endpoint. Category filters cover full web, news, companies, research, people, and financials.

Exa is aimed at developers, AI startups, and enterprise teams building assistants, coding agents, research tools, and GTM workflows. The site cites 500,000 developers building on the platform, and use cases span model training, inference providers, and enterprise search. An API playground lets teams test requests and responses before committing to integration.

For evaluation, start with the free API trial and the playground to compare latency tiers against your own queries. Review the documentation and pricing page to match call volume and depth needs, and check the llms.txt site index for a structured map of products, evaluations, and comparisons. Exa is a strong fit when search quality and real-time grounding matter more than building retrieval in
