description: "Build production-ready Tavily integrations with best practices baked in. Reference documentation for developers using coding assistants to implement web search, content extraction, crawling, and research in agentic workflows, RAG systems, or autonomous agents."

Tavily

Tavily is a search API designed for LLMs, enabling AI applications to access real-time web data.

Installation

**Python:**

pip install tavily-python

**JavaScript:**

npm install @tavily/core

See **[references/sdk.md](references/sdk.md)** for complete SDK reference.

Client Initialization

from tavily import TavilyClient

# Uses TAVILY_API_KEY env var (recommended)
client = TavilyClient()

#With project tracking (for usage organization)
client = TavilyClient(project_id="your-project-id")

# Async client for parallel queries
from tavily import AsyncTavilyClient
async_client = AsyncTavilyClient()

Choosing the Right Method

**For custom agents/workflows:**

| Need | Method | |------|--------| | Web search results | `search()` | | Content from specific URLs | `extract()` | | Content from entire site | `crawl()` | | URL discovery from site | `map()` |

**For out-of-the-box research:**

| Need | Method | |------|--------| | End-to-end research with AI synthesis | `research()` |

Quick Reference

search() - Web Search

response = client.search(
    query="quantum computing breakthroughs",  # Keep under 400 chars
    max_results=10,
    search_depth="advanced"
)
print(response)

Key parameters: `query`, `max_results`, `search_depth` (ultra-fast/fast/basic/advanced), `include_domains`, `exclude_domains`, `time_range`

See **[references/search.md](references/search.md)** for complete search reference.

extract() - URL Content Extraction

# Simple one-step extraction
response = client.extract(
    urls=["https://docs.example.com"],
    extract_depth="advanced"
)
print(response)

Key parameters: `urls` (max 20), `extract_depth`, `query`, `chunks_per_source` (1-5)

See **[references/extract.md](references/extract.md)** for complete extract reference.

crawl() - Site-Wide Extraction

response = client.crawl(
    url="https://docs.example.com",
    instructions="Find API documentation pages",  # Semantic focus
    extract_depth="advanced"
)
print(response)

Key parameters: `url`, `max_depth`, `max_breadth`, `limit`, `instructions`, `chunks_per_source`, `select_paths`, `exclude_paths`

See **[references/crawl.md](references/crawl.md)** for complete crawl reference.

map() - URL Discovery

response = client.map(
    url="https://docs.example.com"
)
print(response)

research() - AI-Powered Research

import time

# For comprehensive multi-topic research
result = client.research(
    input="Analyze competitive landscape for X in SMB market",
    model="pro"  # or "mini" for focused queries, "auto" when unsure
)
request_id = result["request_id"]

# Poll until completed
response = client.get_research(request_id)
while response["status"] not in ["completed", "failed"]:
    time.sleep(10)
    response = client.get_research(request_id)

print(response["content"])  # The research report

Key parameters: `input`, `model` ("mini"/"pro"/"auto"), `stream`, `output_schema`, `citation_format`

See **[references/research.md](references/research.md)** for complete research reference.
