Search API that gives AI agents and LLM apps real-time, semantically relevant web results and clean content extraction.
Exa is a search engine built specifically for AI. Instead of returning links optimized for human clicks, Exa delivers clean, semantically relevant results that AI agents and LLMs can use directly. It supports neural search, keyword search, content extraction, a find-similar endpoint, and an agentic research API. Developers use Exa to power RAG pipelines, AI chatbots, research tools, and lead generation workflows.
Exa is a search engine and API built for AI systems, agents, and developers. It uses semantic (embedding-based) search to retrieve and return relevant web content in a clean, structured format that is easy for large language models to use. Exa is designed for retrieval workflows such as RAG systems, AI agents, and research tools rather than human web browsing.
Exa uses neural embeddings to understand query intent, not just keywords. It returns parsed, clean content ready for LLM consumption instead of ad-laden search result pages. Users also report it is significantly cheaper than Google's Search API for AI use cases.
Exa offers a free tier with 1,000 searches per month. The API pricing is $7 per 1,000 requests with 10 results (including text and highlights), plus $1 per 1,000 additional results. A Pro plan starts at $40/month, and enterprise pricing is available on request. Websets, their no-code list-building product, starts at $49/month.
Exa provides official SDKs for Python and JavaScript. It also integrates natively with popular AI frameworks including LangChain, LlamaIndex, CrewAI, and the Vercel AI SDK. An MCP server is available for direct connection to Claude and other AI assistants.
Exa Research is an agentic search feature launched in June 2025 that automates iterative querying, reading, clustering, and summarization. Instead of a single search call, it performs multi-step research and returns structured JSON results with citations.
Websets is Exa's no-code product for go-to-market teams. You describe what you're looking for in plain language, and Websets builds enriched lists of companies or people with data like emails, phone numbers, funding info, and custom categories. It's a separate product from the search API with its own pricing.
Exa powers search for AI products including Cursor and Notion AI. It is used by developers building RAG systems, AI agents, research tools, and lead generation workflows. Their specialized indexes serve investors, recruiters, sales teams, and AI researchers.
Yes. By providing verified, real-time web content directly to your LLM, Exa helps ground responses in actual data. Their Highlights feature further reduces hallucination by extracting only the most relevant tokens from web pages, giving models focused context instead of noisy full-page content.
