Tavily is a production-grade web search and data retrieval API purpose-built for AI agents, LLMs, and Retrieval-Augmented Generation (RAG) pipelines. Unlike traditional search engines that return raw web pages designed for human readers, Tavily delivers structured, chunked, and citation-ready content optimized for language model consumption — eliminating hallucinations and reducing context-window waste. The platform unifies real-time search, content extraction, automated research, and web crawling behind a single secure API, with intelligent caching, content validation, and security layers that block PII leakage, prompt-injection attempts, and malicious sources. Developers can integrate Tavily with a few lines of code through native SDKs for Python and JavaScript, as well as first-class integrations with LangChain, LlamaIndex, CrewAI, AutoGen, and the broader agent ecosystem. Key capabilities include the Search API for live web answers with source attribution, the Extract API for converting URLs into clean Markdown, the Crawl API for site-wide retrieval, and an autonomous Research endpoint that iteratively deepens queries until an answer is reached. With 1,000 free credits monthly, predictable pay-as-you-go pricing, and SOC 2-aligned infrastructure, Tavily has become one of the default search backends powering AI agents at startups and enterprises building grounded, real-time AI applications in 2026.
