Tavily Tools

When to use which tool

Need	Tool	When
Quick web search	web_search	Basic queries, no special options needed
Search with advanced options	tavily_search	Need depth, topic, domain filters, time ranges, or AI answers
Extract content from URLs	tavily_extract	Have specific URLs, need their content

web_search

Tavily powers this automatically when selected as the search provider. Use for straightforward queries where you don't need Tavily-specific options.

Parameter	Description
query	Search query string
count	Number of results (1-20)

tavily_search

Use when you need fine-grained control over search behavior.

Parameter	Description
query	Search query string (keep under 400 characters)
search_depth	basic (default, balanced) or advanced (highest relevance, slower)
topic	general (default), news (real-time updates), or finance
max_results	Number of results, 1-20 (default: 5)
include_answer	Include an AI-generated answer summary (default: false)
time_range	Filter by recency: day, week, month, or year
include_domains	Array of domains to restrict results to
exclude_domains	Array of domains to exclude from results

Search depth

Depth	Speed	Relevance	Best for
basic	Faster	High	General-purpose queries (default)
advanced	Slower	Highest	Precision, specific facts, detailed research

Tips

• Keep queries under 400 characters — think search query, not prompt.
• Break complex queries into sub-queries for better results.
• Use include_domains to focus on trusted sources.
• Use time_range for recent information (news, current events).
• Use include_answer when you need a quick synthesized answer.

tavily_extract

Use when you have specific URLs and need their content. Handles JavaScript-rendered pages and returns clean markdown. Supports query-focused chunking for targeted extraction.

Parameter	Description
urls	Array of URLs to extract (1-20 per request)
query	Rerank extracted chunks by relevance to this query
extract_depth	basic (default, fast) or advanced (for JS-heavy pages, tables)
chunks_per_source	Chunks per URL, 1-5 (requires query)
include_images	Include image URLs in results (default: false)

Extract depth

Depth	When to use
basic	Simple pages — try this first
advanced	JS-rendered SPAs, dynamic content, tables, embedded content

Tips

• Max 20 URLs per request — batch larger lists into multiple calls.
• Use query + chunks_per_source to get only relevant content instead of full pages.
• Try basic first, fall back to advanced if content is missing or incomplete.
• If tavily_search results already contain the snippets you need, skip the extract step.

Choosing the right workflow

Follow this escalation pattern — start simple, escalate only when needed:

1. web_search — Quick lookup, no special options needed.
2. tavily_search — Need depth control, topic filtering, domain filters, time ranges, or AI answers.
3. tavily_extract — Have specific URLs, need their full content or targeted chunks.

Combine search + extract when you need to find pages first, then get their full content.
