Tavily

Tavily is an AI-optimized search API designed specifically for use by AI agents and LLM-powered applications. Founded to solve the problem of giving AI systems access to current, high-quality web information, Tavily has become one of the most popular search tools in the AI agent ecosystem.

Tavily's API is optimized for LLM consumption — returning clean, structured search results with extracted content, relevance scores, and source URLs that AI agents can directly use for research, fact-checking, and information gathering. Unlike traditional search APIs that return HTML snippets, Tavily extracts and cleans the actual content, saving tokens and improving AI response quality. The API supports both basic search and deep research modes.

Tavily has become a standard tool in the AI agent toolkit, with native integrations in LangChain, LlamaIndex, CrewAI, and other agent frameworks. The company's focus on AI-first search (rather than adapting a human-oriented search engine for AI use) has made it the go-to choice for developers building AI agents that need to search the web — a rapidly growing use case as autonomous AI agents become more capable and common.
