Tavily
AI-native search API that delivers real-time, grounded results optimized for agents and RAG pipelines.
About
Tavily bills itself as "the web access layer for agents" — a search, extraction, and crawling API built specifically for AI agent workflows. When an agent queries Tavily, it gets synthesized, grounded results rather than raw links, with built-in protections against PII leakage and prompt injection. The Research endpoint can perform autonomous multi-step research tasks, achieving state-of-the-art benchmarks on factuality.
The platform has been widely adopted across the agent ecosystem, with over a million developers and 100 million monthly requests. Tavily has an official OpenClaw skill, native integrations with LangChain and LlamaIndex, and partnerships with IBM, JetBrains, and Databricks. Agents connect via REST API with bearer token auth, through the official MCP server, or via drop-in integrations with OpenAI and Anthropic SDKs.
Tavily offers a genuinely free tier — 1,000 API credits per month with no credit card required — making it one of the easiest search APIs for agents to start using immediately. Paid plans start at $0.008 per credit with higher rate limits.
