When to Use

Building RAG applications with real-time web data
AI agents that need current information
Content extraction from web pages
Site crawling with AI-guided instructions
Autonomous research tasks

Installation

Install: pip install tavily-python (Python) or npm i @tavily/core (JavaScript).

Quick Start

Python

from tavily import TavilyClient

client = TavilyClient(api_key="tvly-YOUR_API_KEY")
response = client.search("What is the latest news about AI?")
print(response)

JavaScript

import { tavily } from "@tavily/core";

const client = tavily({ apiKey: "tvly-YOUR_API_KEY" });
const response = await client.search("What is the latest news about AI?");
console.log(response);

cURL

curl -X POST https://api.tavily.com/search \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer tvly-YOUR_API_KEY" \
  -d '{"query": "What is the latest news about AI?"}'

Note: Crawl endpoint limited to 100 RPM for both environments.

Production keys require paid plan or PAYGO enabled.

Search API

Primary endpoint for LLM-optimized web search.

response = client.search(
    query="Latest AI developments",
    search_depth="advanced",      # "basic" (1 credit) or "advanced" (2 credits)
    max_results=10,               # 1-20 results
    include_answer=True,          # Include AI-generated answer
    include_raw_content=False,    # Include raw HTML
    include_domains=["arxiv.org"],  # Filter to specific domains
    exclude_domains=["pinterest.com"]  # Exclude domains
)

Response Structure

{
    "query": "...",
    "answer": "AI-generated summary...",  # if include_answer=True
    "results": [
        {
            "title": "Page Title",
            "url": "https://...",
            "content": "Extracted relevant content...",
            "score": 0.95,
            "raw_content": "..."  # if include_raw_content=True
        }
    ]
}

Extract API

Extract content from specific URLs.

response = client.extract(
    urls=["https://example.com/article1", "https://example.com/article2"],
    extract_depth="basic"  # "basic" or "advanced"
)

Crawl API

Crawl websites with AI-guided instructions.

response = client.crawl(
    url="https://docs.example.com",
    instructions="Find all pages about Python SDK",  # Optional AI guidance
    max_depth=2,
    limit=50
)

Map API

Get website structure without extracting content.

response = client.map(
    url="https://docs.example.com",
    instructions="Find documentation pages"  # Optional
)

Research API (Beta)

Autonomous deep research on complex topics.

response = client.research(
    input="What are the implications of quantum computing on cryptography?",
    model="pro"  # "pro" (15-250 credits) or "mini" (4-110 credits)
)

Why Tavily?

| Feature | Traditional Search | Tavily | | ---------------- | ------------------ | ------------- | | Output | URLs + snippets | Full content | | Scraping | Manual | Built-in | | LLM optimization | None | Purpose-built | | Filtering | Manual | AI-powered | | Context limits | Not handled | Optimized |

Best Practices

Use search_depth="basic" for simple queries (saves credits)
Use include_answer=True for quick summaries
Filter domains to improve relevance
Use Extract when you know specific URLs
Use Research for complex, multi-step queries

Prohibitions

Do not expose API keys in client-side code
Do not exceed rate limits (implement backoff)
Do not scrape sites that block Tavily crawler
