Exa is a powerful, specialized API for developers who need to ground their LLM applications in real-time web data. While not a consumer search tool, it's a critical piece of infrastructure for building sophisticated AI agents.
An API that enables AI agents to reason over the web by providing reliable, real-time access to information through a search engine built for LLMs.
Exa, formerly known as Metaphor, is a knowledge API designed to connect Large Language Models (LLMs) with the live, up-to-date web. Unlike traditional search engines that rely on keywords, Exa functions as a 'search engine for LLMs,' allowing developers to query the internet using natural language and semantic concepts. The API takes a descriptive prompt about the desired information and returns a list of relevant links along with their clean HTML content, ready for an AI agent to process. This platform is built specifically for developers, AI engineers, and companies creating AI-powered applications. It is an essential tool for building agents that require real-time information for tasks like research, analysis, or providing grounded answers. By offering official SDKs in Python and JavaScript/TypeScript, and integrations with popular frameworks like LangChain and LlamaIndex, Exa aims to be the go-to infrastructure layer for giving AI applications reliable access to the world's knowledge.
Developers, AI engineers, and companies building AI agents that require real-time web access and knowledge retrieval.
