Search API built for AI agents and LLM applications
Tavily is a search engine and API purpose-built for AI agents and large language model applications. Unlike traditional search APIs that return raw HTML or link lists, Tavily returns pre-processed, AI-optimized search results with extracted content, relevance scoring, and source citations ready for LLM consumption. This makes it the go-to search tool for building RAG (Retrieval-Augmented Generation) pipelines, research agents, and grounded AI applications. In 2026, Tavily added Deep Search (multi-step research like Perplexity), real-time news search, academic paper search, and custom domain filtering. It integrates natively with LangChain, LlamaIndex, OpenAI function calling, and CrewAI. Many of the top AI agent frameworks use Tavily as their default search tool.
Free tier includes 1,000 searches/month. Researcher plan $50/month for 10,000 searches. Scale plan custom pricing for high volume.
