The Zerion CLI is an open-source tool that wraps the Zerion API. It’s designed for both humans and AI agents — any agent that can run shell commands can query wallets, tokens, and chains without writing API integration code. Repository: github.com/zeriontech/zerion-ai

​
Installation

npm install -g zerion-cli
Then set your API key: 
export ZERION_API_KEY="zk_dev_..."
Get a free key from the Zerion Dashboard.

Usage

zerion-cli wallet analyze 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045
This returns a summary of the wallet’s total portfolio value, top positions, recent transactions, and PnL.

​
Usage by AI agents

AI coding assistants (Claude, Cursor, etc.) and autonomous agents can invoke the CLI as a shell tool. No HTTP client setup, no auth header construction — just structured output from a single command. Good fits:
  • Agents that need onchain context during a task (e.g. check a wallet before executing a transaction)
  • Pipelines that enrich data with portfolio or position information
  • x402-based flows where the CLI handles the payment handshake automatically
