Zerion CLI

Crypto portfolios are fragmented. Dozens of chains, thousands of protocols, multiple wallets. Tracking everything means clicking through tabs, switching apps, and creating spreadsheets. Getting answers is slow.

That’s changing. You can give Claude data, ask questions, and get answers in plain language. The main bottleneck is feeding this data. 

Zerion was founded on a simple idea: unify finance in a single interface. The interfaces are changing, but the idea is the same.

Today, we are releasing Zerion CLI, an open-source toolkit that gives Claude Code, Cursor, Codex, and other AI agents the ability to manage portfolios, swap tokens, and sign transactions across 40+ chains. The first technical interface is available now with a one-line install:

npx -y zerion-cli init

What Zerion CLI does

Out of the box, with Zerion CLI, any compatible agent can:

  • Pull the full crypto portfolio context, including balances, DeFi positions across 8,000+ protocols, transactions, and PnL across 40+ EVM chains and Solana
  • Search assets, quote swaps, route bridges, and send tokens
  • Sign messages and transactions, with private keys staying on your device

Zerion CLI runs on Zerion API, the same infrastructure that powers portfolio data inside Coinbase, Uniswap, OpenSea, Safe, Kraken, and 2000+ onchain products. 

Three authentication models are supported: standard API keys for production use, x402 for agentic payments on Base or Solana with no signup required, and Machine Payment Protocol on Tempo.

What people are doing with it

Here are the workflows that have surfaced first:

  • Portfolio tracking. Ask the agent what is in your wallets across 40+ chains. Drill into protocols, tokens, or any cut you can describe in plain language.
  • Wallet monitoring. Track addresses you care about and ask questions about their activity.
  • Market context. Pull current prices, protocol stats, and onchain activity into your existing agent workflow.
  • Tax prep. Pull transactions across chains and wallets, classify them, and calculate realized PnL.
  • Agent-assisted trading. Ask your AI agent to monitor prices and prepare a swap for your confirmation, with a full quote preview and simulation before anything is signed.

The common thread: Zerion supplies the portfolio and wallet data, your agent does the rest.

Open source and extendable

Zerion Skills are how Zerion CLI grows. Skills are modules that add new protocols, workflows, and integrations. 

MoonPay, Uniswap, Polymarket, Monad, LI.FI and more have contributed Skills at launch, with more partners onboarding on a rolling basis.

You can ship one too. Open a PR to the /skills folder, and your integration becomes available to every AI agent running Zerion CLI.

Get started

Install the Zerion CLI, point it at your wallet, and the agent you already use becomes a crypto-native one:

npx -y zerion-cli init

The most interesting use cases will come from things we have not thought of. We'll be in the issues, the PRs, and the comments. It's the start of something we want to build with you.
