Best for AI developers building agents or RAG systems that need clean, structured web search results without scraping raw HTML.
Use Cases
Free Tier
1,000 API credits/month on the Researcher plan, no credit card required
How to Maximize the Free Tier
Tavily's 1,000 free credits go further if you use basic search (1 credit) instead of advanced search (2 credits) unless you specifically need the extra depth. Cache extracted URLs locally — the /extract endpoint is powerful but costs 1 credit per URL, so avoid re-extracting the same pages. Use the include_domains parameter to narrow searches to specific sites, reducing irrelevant results and wasted credits. The Researcher plan is ideal for prototyping and side projects; upgrade to Project only when you need higher rate limits for production workloads.
Getting Started
Sign up at tavily.com → get API key instantly (no credit card) → call the /search endpoint with your query → receive structured JSON with titles, URLs, content snippets, and relevance scores → use /extract endpoint to pull full content from specific URLs.
Pros
- No credit card: Truly free signup with no payment information required — rare among search API providers
- AI-native output: Results come pre-cleaned and structured for LLM consumption — no HTML parsing or content extraction needed
- Extract endpoint: Built-in URL extraction pulls full page content and returns it as clean text, eliminating the need for a separate scraper
Cons
- AI-focused: Not designed for traditional site search or e-commerce product search — strictly a web search API for AI use cases
- Credit consumption: Advanced search depth and extract operations cost more credits — a single deep search uses 2 credits instead of 1
- Startup maturity: Relatively new service compared to established APIs — documentation and SDK coverage are still growing
