zerion-ai

Maintained by Zerion.

zerion-ai is the public, self-contained repo for using Zerion from AI agents and developer tools.

It packages two first-class integration paths:

• Hosted MCP for Cursor, Claude, and other MCP-native agent environments
• zerion-cli for OpenClaw-like and command-based agent runtimes

It also ships one flagship workflow:

• wallet-analysis as a reusable skill/playbook for portfolio, positions, transactions, and PnL analysis

1. Choose your authentication method

Option A: API Key

Get an API key and export it: Get your API key

export ZERION_API_KEY="zk_dev_..."

• API auth via HTTP Basic Auth
• dev keys beginning with zk_dev_
• current dev-key limits of 120 requests/minute and 5k requests/day

Useful docs:

• Build with AI
• Get Wallet Data With Zerion API

Option B: x402 Pay-per-call

No API key needed. Pay $0.01 USDC per request on Base via the x402 protocol. The CLI handles the payment handshake automatically using your wallet's private key.

Setup:

export WALLET_PRIVATE_KEY="0x..."   # EVM wallet with USDC on Base

Then use the --x402 flag:

zerion-cli wallet analyze 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 --x402

Or enable x402 globally:

export ZERION_X402=true
zerion-cli wallet analyze 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045

2. Install skills (Claude Code, Cursor, OpenClaw)

npx skills add zeriontech/zerion-ai

This installs 3 skills into your agent:

The skills reference zerion-cli which runs via npx zerion-cli (no global install needed).

3. Choose your integration path

MCP clients

Use this if your agent runtime already supports MCP.

Start here:

• Hosted MCP quickstart
• Cursor example
• Claude example

OpenClaw and CLI-based agents

Use this if your framework models tools as shell commands returning JSON.

npm install -g zerion-cli
zerion-cli wallet analyze 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045

Start here:

• OpenClaw example
• CLI usage

4. Run the first wallet analysis

MCP quickstart

1. Export your API key:

   export ZERION_API_KEY="zk_dev_..."
   

2. Add the hosted Zerion MCP config from examples/cursor/mcp.json or examples/claude/mcp.json

3. Ask:

   Analyze the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045.
   Summarize total portfolio value, top positions, recent transactions, and PnL.
   

CLI quickstart

With API key:

npm install -g zerion-cli
export ZERION_API_KEY="zk_dev_..."
zerion-cli wallet analyze 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045

With x402 (no API key needed):

npm install -g zerion-cli
export WALLET_PRIVATE_KEY="0x..."
zerion-cli wallet analyze 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 --x402

Example output:

{
  "wallet": {
    "query": "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045"
  },
  "portfolio": {
    "total": 450000,
    "currency": "usd"
  },
  "positions": {
    "count": 42
  },
  "transactions": {
    "sampled": 10
  },
  "pnl": {
    "available": true
  }
}

Example wallets

This repo uses the same public wallets across examples:

• vitalik.eth / 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045
• ENS DAO treasury / 0xFe89Cc7Abb2C4183683Ab71653c4cCd1b9cC194e
• Aave collector / 0x25F2226B597E8F9514B3F68F00F494CF4F286491

What ships in this repo

• skills/: 3 agent skills installable via npx skills add zeriontech/zerion-ai
  • wallet-analysis/: portfolio, positions, transactions, and PnL analysis
  • chains/: supported blockchain networks reference
  • zerion-cli/: CLI setup, auth, and troubleshooting
• mcp/: hosted Zerion MCP setup plus the tool catalog
• cli/: zerion-cli JSON-first CLI (published to npm)
• examples/: Cursor, Claude, OpenAI Agents SDK, raw HTTP, and OpenClaw setups

Failure modes to expect

Both the MCP and CLI surfaces should handle:

• missing or invalid API key
• invalid wallet address
• unsupported chain filter
• empty wallets / no positions
• rate limits (429)
• upstream timeout or temporary unavailability

See mcp/README.md and cli/README.md for the concrete behavior used in this repo.
