Overview

kagi-cli is a terminal CLI that provides command-line access to Kagi search, Quick Answer, AI Assistant, translation, summarization, public feeds through news and smallweb, and account-level search settings like lenses, custom assistants, custom bangs, and redirects. It outputs JSON by default for scripting and automation, with --format pretty for human-readable terminal output on the commands that support alternate renderers.

The CLI prioritizes the subscriber session-token path, so existing Kagi subscribers can use most features without paying for API access. Current /api/v1 Search and Extract features use KAGI_API_KEY; legacy paid API features (summarize, fastgpt, enrich) use KAGI_API_TOKEN.

Installation

# Homebrew (macOS/Linux)
brew tap Microck/kagi
brew install kagi

# Scoop (Windows)
scoop bucket add kagi https://github.com/Microck/scoop-kagi
scoop install kagi

# npm (cross-platform)
npm install -g kagi-cli

# Direct install (macOS/Linux)
curl -fsSL https://raw.githubusercontent.com/Microck/kagi-cli/main/scripts/install.sh | sh

# Direct install (Windows PowerShell)
irm https://raw.githubusercontent.com/Microck/kagi-cli/main/scripts/install.ps1 | iex

Authentication

Interactive Setup (Recommended)

kagi auth

Opens a guided TTY wizard that walks through:

• Choosing Session Link, API Key, or Legacy API Token
• Pasting credentials
• Saving to ~/.config/kagi-cli/config.toml
• Immediate validation

Non-Interactive Setup

# Session token (from https://kagi.com/settings/user_details)
kagi auth set --session-token 'https://kagi.com/search?token=...'

# Or via environment variable
export KAGI_SESSION_TOKEN='...'

# API key for current /api/v1 endpoints (from https://kagi.com/api/keys)
export KAGI_API_KEY='...'

# Legacy API token for /api/v0 endpoints (from https://kagi.com/settings/api)
export KAGI_API_TOKEN='...'

Auth Model

Credential	What It Unlocks
KAGI_SESSION_TOKEN	base search fallback, search --lens, search --news, session-only search options, quick, ask-page, assistant, translate, summarize --subscriber
KAGI_API_KEY	current /api/v1 Search API and Extract API
KAGI_API_TOKEN	summarize, fastgpt, enrich web, enrich news
none	news, smallweb, auth status, --help

Environment variables override ~/.config/kagi-cli/config.toml. When a session token and API key are both present, base kagi search defaults to the session token; set [auth] preferred_auth = "api" in config to prefer the API key.
