Tavily is a real-time web search API purpose-built for AI agents and LLM pipelines. It delivers structured, chunked web content optimized for LLM consumption, with a p50 latency of 180ms and a 99.99% uptime SLA. The API handles 300M+ monthly requests and includes built-in security layers — PII detection and prompt injection blocking — so developers don't need to bolt on separate safeguards. Tavily is open source (2,417 GitHub stars) and integrates natively with major AI ecosystems including OpenAI, Anthropic, Groq, Databricks, IBM WatsonX, JetBrains, Nebius, and MCP. Pricing starts on a freemium model: 1,000 API credits/month free (no credit card required), with Pay As You Go at $0.008/credit, a Project plan with 4,000 credits/month, and custom Enterprise tiers.
