Tavily is a search API built specifically for AI agents and LLM applications that need real-time web information. Unlike general web search APIs (Google, Bing) that return HTML-heavy results optimised for human browser rendering, Tavily returns clean, structured content optimised for LLM consumption — extracting the relevant text from each result without the navigation, advertising, and HTML markup that confuse LLM parsers.
For AI agents and RAG applications that need to search the web to answer questions or gather information, Tavily provides a cleaner input than scraping Google results or using the general Bing API. The search results include pre-extracted clean text, relevance scores, and structured metadata that allow agents to immediately use the content without additional parsing.
The topic filter allows specifying whether to search general web, news, or specific topic categories, giving agents more precise search control. The include_answer parameter returns an AI-synthesised answer alongside the source documents, combining Perplexity-style grounded AI answers with raw source access.
At 1,000 free API calls per month, Tavily is accessible for developers building and evaluating RAG applications. The Basic plan at $35/month for 5,000 calls covers moderate production use.
Tavily is widely adopted in the LangChain, LlamaIndex, and CrewAI ecosystems as the recommended search tool for AI agent web search capability, with native integrations across these frameworks.
Tavily AI runs as ai search software built around text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on web and api, with API access for teams that want to embed it into their own products.
