Tavily CLI

CLI and agent tools for the Tavily API — search, extract, crawl, map, and research from the command line.

Note: This package provides the tvly command-line tool. It depends on tavily-python, the official Tavily Python SDK.

Features

• Interactive REPL — Run tvly with no arguments for a chat-like shell experience
• CLI for Humans & AI Agents — Rich-formatted output for humans, --json for agents
• Web Search — LLM-optimized search with domain/date filtering and relevance scoring
• Content Extraction — Extract clean markdown from any URL
• Website Crawling — Crawl sites with depth/breadth control and path filtering
• URL Discovery — Map all URLs on a site without content extraction
• Deep Research — AI-powered research with citations and structured output

Installation

Requires Python 3.10+.

pip install tavily-cli

From source

git clone https://github.com/tavily-ai/tavily-cli.git
cd tavily-cli
pip install -e .

Quick Start

1. Authenticate

# Set API key directly
tvly login --api-key tvly-YOUR_KEY

# Or use environment variable
export TAVILY_API_KEY=tvly-YOUR_KEY

# Or OAuth (opens browser)
tvly login

# Check auth status
tvly auth

2. Interactive Mode

# Launch the interactive REPL
tvly

This opens a chat-like shell where you can run commands without the tvly prefix:

❯  search "latest AI trends"
❯  extract https://example.com
❯  help

3. Search the Web

# Basic search
tvly search "latest AI trends"

# Advanced search with filters
tvly search "quantum computing" --depth advanced --max-results 10 --time-range week

# Search specific domains
tvly search "SEC filings for Apple" --include-domains sec.gov,reuters.com

# JSON output for agents
tvly search "AI news" --json

4. Extract Content from URLs

# Extract a single URL
tvly extract https://example.com/article

# Extract multiple URLs with a focus query
tvly extract https://example.com https://other.com --query "pricing information"

# Advanced extraction for JS-heavy pages
tvly extract https://spa-app.com --extract-depth advanced

5. Crawl a Website

# Basic crawl
tvly crawl https://docs.example.com

# Deep crawl with filters
tvly crawl https://docs.example.com --max-depth 2 --limit 100 --select-paths "/api/.*,/guides/.*"

# Semantic focus
tvly crawl https://docs.example.com --instructions "Find authentication docs" --chunks-per-source 3

# Save pages as markdown files
tvly crawl https://docs.example.com --output-dir ./docs

6. Map URLs

# Discover all URLs on a site
tvly map https://example.com

# Filter by path
tvly map https://example.com --select-paths "/blog/.*" --limit 500

7. Deep Research

# Run research and wait for results
tvly research "Competitive landscape of AI code assistants"

# Use pro model for comprehensive analysis
tvly research "Electric vehicle market analysis" --model pro

# Stream results in real-time
tvly research "AI market trends" --stream

# Async: start and poll separately
tvly research "topic" --no-wait --json        # returns request_id
tvly research status <request_id> --json      # check status
tvly research poll <request_id> --json        # wait and get result

# Structured output
tvly research "AI market size" --output-schema schema.json --json

Non-Interactive Mode (for AI Agents & Scripts)

All commands support --json output and can be fully controlled via CLI arguments.

# Every command supports --json for structured output
tvly search "query" --json
tvly auth --json
tvly extract https://example.com --json

# Read input from stdin with "-"
echo "What is the latest funding for Anthropic?" | tvly search - --json
echo "Research question" | tvly research - --json

# Async research: launch then poll separately
tvly research "question" --no-wait --json        # returns request_id
tvly research status <id> --json                 # check status
tvly research poll <id> --json                   # wait and get result

# Global options
tvly --version         # show version
tvly --status          # show version + auth status
tvly --status --json   # structured status
