Tavily
Tavily is a web search and extraction API built for AI agents and RAG pipelines. One REST API covers search, extract, crawl, research, and map endpoints so agents can pull live web data, chunk it for models, and cite sources without building a scraper stack. The company reports 300M+ monthly requests, a 180 ms p50 on /search, and 99.99% uptime for production workloads.
Most general search APIs return links and snippets. Tavily targets agent workflows: it ranks #1 on Virginia Tech's SealQA benchmark for search-augmented reasoning under noisy results, ships content validation that blocks PII and prompt injection before data reaches your model, and adds a /research endpoint for multi-step deep research. That narrow focus trades breadth of consumer search features for retrieval tuned to LLM grounding.
Developers wiring LangChain, OpenAI, Anthropic, or Groq agents use Tavily when answers need fresh facts. Teams in sales, finance, legal, security, and recruiting lean on the same API for meeting briefs, competitive tracking, investment memos, regulatory monitoring, and threat intel, all backed by live web sources rather than stale databases.
Five endpoints (search, extract, crawl, research, map) through one REST API with Python and JavaScript SDKs
180 ms p50 latency on /search with 300M+ monthly requests and 99.99% uptime SLA
Built-in PII blocking, prompt injection filters, and malicious source validation before results reach models
Researcher free plan includes 1,000 API credits per month with no credit card required
Drop-in integration with OpenAI, Anthropic, and Groq for agent and RAG workflows
Ranks #1 on Virginia Tech SealQA for search-augmented reasoning under conflicting web results
Five web access endpoints (search, extract, crawl, research, map) from one API instead of stitching multiple vendors.
Free Researcher tier includes 1,000 API credits monthly with no credit card.
Production safeguards block PII leakage, prompt injection, and malicious sources before data reaches models.
180 ms p50 /search latency at 300M+ monthly requests with a 99.99% uptime SLA.
API requests halt when monthly credits run out unless you upgrade to a paid tier.
Enterprise limits and pricing require a custom sales conversation.
Credit consumption varies by endpoint type, so cost planning takes more effort than flat-rate search APIs.
What does Tavily do for AI agents?
Tavily connects AI agents to the live web through a single API. Its search, extract, crawl, research, and map endpoints return structured, chunked content so models can ground answers in current sources instead of stale training data.
How much does Tavily cost?
Tavily's Researcher plan is free with 1,000 API credits per month and no credit card. Pay As You Go costs $0.008 per credit, the Project tier offers 4,000 monthly credits on a slider-based plan, and Enterprise pricing is custom.
Does Tavily require a credit card on the free plan?
No. Tavily's free Researcher plan gives you 1,000 API credits each month without entering a credit card. Sign up, grab an API key from the dashboard, and install the Python or JavaScript SDK to start calling the API.
What happens when Tavily API credits run out?
When Tavily monthly credits are exhausted, API requests stop until credits reset on the first of the month or you move to a paid plan. Paid tiers raise monthly limits and keep usage uninterrupted.
Which Tavily API endpoints are available?
Tavily exposes search for fast web results, extract for clean page content, crawl for whole-site extraction, research for multi-step deep research, and map for discovering URLs across a domain. Credit usage depends on the endpoint and request volume.
Who uses Tavily in production?
Tavily reports 2M+ developers and customers including LangChain, MongoDB, Groq, JetBrains, IBM, AWS, and Mastercard. Teams use it for sales briefs, investment research, legal monitoring, threat intel, and open-source agent projects.
