Zerion CLI is an open source toolkit of commands and Skills that gives AI agents onchain capabilities. One install adds wallet analysis, swaps, wallet management, transaction signing, and policy controls to Claude Code, Cursor, Codex, and any compatible client. It is powered by Zerion's data infrastructure and works across 40+ EVM chains and Solana.

CLI stands for Command Line Interface. It's a program that an agent or its human operator can launch from a computer terminal. Zerion CLI packages Zerion's wallet, swap, and signing tools into short commands that are optimized for AI agents.

Which AI agents work with Zerion CLI?

Zerion CLI works with every agent harness or framework that can access terminal and skills: Claude Code, Cursor, Codex, OpenClaw, and more. Install once with `npx -y zerion-cli init -y --browser` and the same skills become available in every client on your machine.

Which blockchains does Zerion CLI support?

Zerion CLI supports 40+ EVM chains plus Solana, including Ethereum, Base, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, and Monad. Coverage matches Zerion's data infrastructure, which already powers wallet experiences for Coinbase Wallet, Uniswap, Kraken, and Safe.

Can Zerion CLI sign and send transactions?

Yes. Zerion CLI can create agent-scoped wallets, sign EIP-712 typed data, and broadcast transactions onchain. You can also attach security policies — flags that constrain what a wallet can sign, what chains it can use, and when permissions expire.

How much does Zerion CLI cost?

Zerion CLI is free to install. For API access, you can authenticate in three ways: a standard API key with higher rate limits for production, x402 micropayments at $0.01 per call on Base or Solana with no signup, or MPP at $0.01 per call on Tempo.
