Exa

Exa is a real-time AI-powered search engine that provides a suite of APIs designed specifically for AI agents, developers, and researchers who need structured, high-quality web data at scale. Unlike traditional search engines that focus on user-facing results, Exa’s core offering is a programmatic search interface that returns machine-readable outputs—such as JSON objects containing relevant URLs, titles, snippets, and metadata—enabling direct integration into automated workflows, chatbots, code assistants, and research pipelines. The platform includes three primary APIs: the Search API, the Crawling API, and the SERP API. The Search API allows developers to query the web with natural language or structured parameters, returning results ranked by relevance and recency. It supports multiple verticals, including full web searches, news, companies, research papers, people profiles, and financial data, each optimized for specific use cases. For instance, a financial analyst can retrieve the latest earnings reports and SEC filings, while a researcher can find academic preprints and citations. The Crawling API goes a step further: it extracts full structured content from given URLs, converting raw HTML into clean, parsed text, tables, and images. This is particularly useful for building knowledge graphs, training datasets, or monitoring competitor websites. The SERP API mimics traditional search engine result pages but delivers structured data (title, description, link, position) that can be used for SEO analysis, trend tracking, or building custom search widgets. Exa is built for speed. The standard search latency is around 450 milliseconds, with an automatic mode that adjusts between 1 second and a deeper, more comprehensive mode that takes roughly 10 seconds for in-depth r
