Tavily
Officially listedReal-time search API platform purpose-built for AI agents and RAG systems, with high accuracy.
Tavily
Tavily is a real-time web search API platform built for AI agents and large language models, positioned as "internet infrastructure for AI agents". Unlike traditional search APIs that return raw results, Tavily serves LLM-optimized, structured search results ready for direct use by AI models, effectively reducing hallucinations. It serves over 1 million developers and processes more than 100 million requests per month.
Core Capabilities
- Five API endpoints: search (web search), extract (content extraction), crawl and map (intelligent site navigation), and research (deep research)
- Industry-leading accuracy: 93.3% on the SimpleQA benchmark, beating Perplexity (85.92%) and Google (82.15%)
- Ultra-fast responses: p50 latency of just 180 milliseconds, with a 99.99% uptime SLA
- Native framework integration: Default search API for LangChain and LlamaIndex, with over 3 million SDK downloads per month
- Enterprise-grade security: Built-in safeguards block PII leaks, prompt injection, and malicious sources
Use Cases RAG system building, AI agent development, chatbots, data enrichment, company research, and market analysis. Fits AI application scenarios that need real-time web data and high accuracy.
Unique Advantages A dual lead in both accuracy and cost efficiency: $0.0005 per query (market low) with 93.3% accuracy (market high). Its graph-based crawling technology explores hundreds of site paths in parallel, and its AI scoring system evaluates up to 20 sources at once.
Editor's Review Tavily stands out in the AI search API market for exceptional accuracy and excellent cost efficiency, making it a top choice for building production-grade RAG systems and AI agents. Although its February 2026 acquisition by Nebius for $275 million adds some uncertainty, service quality has remained stable. It is trusted by Fortune 500 companies including Databricks, IBM, JetBrains, Cohere, and Groq. A generous free tier (1,000 credits/month) and free student access make it the developer-friendly first pick.
