Installation

npm (Global Install)

Install the CLI globally to use the lifi command anywhere:

npm install -g @lifi/cli

Verify the installation:

lifi health

Run any CLI command without installing:

npx @lifi/cli chains
npx @lifi/cli quote --from 1 --to 8453 --from-token USDC --to-token USDC --amount 1000000000

All configuration is via environment variables. No config files needed.

Set your LI.FI API key for higher rate limits:

export LIFI_API_KEY=your_key_here

Configuration	Rate Limit
No API key (public)	200 requests / 2 hours
With API key	200 requests / minute

lifi auth show    # Display masked key
lifi auth test    # Validate key against the API

Run the health check to verify API connectivity:

lifi health

List supported chains to confirm everything works:

lifi chains

If both commands return data successfully, your CLI is ready to use.
