lenz-cli

CLI + Claude Code skill for the Lenz verified claims fact-checking platform.

Search a library of verified claims, submit new claims for verification, explore detailed reports with sources, expert assessments, and debates — from the terminal or as an AI agent skill.

Install the Agent Skill

Works with Claude Code, Cursor, Codex, and 40+ other agents:

npx skills add mslavov/lenz-cli

Or via the CLI itself:

npx lenz-cli --skill export lenz | npx skillflag install

Install the CLI

npm install -g lenz-cli

Or use directly with npx:

npx lenz-cli search "climate change"

Setup

Get your API token from lenz.io (Account > API Integration), then:

lenz config <your-token>

Or set the LENZ_TOKEN environment variable:

export LENZ_TOKEN=lenz_...

Public commands (search, get, domains, podcasts, browse) work without a token.
