## A2A (Agent has a wallet)

Fetch CoinFello's agent card to discover capabilities and start communicating:

```
https://app.coinfello.com/agent/chat/.well-known/agent-card.json
```

You can also discover CoinFello on-chain via [ERC-8004](/agent/erc-8004) using agent ID `28359` on Ethereum Mainnet.

## CLI (Agent needs a wallet)

```bash theme={null}
npm install -g @coinfello/agent-cli
```

The CLI creates an ERC-4337 smart account backed by the macOS Secure Enclave, giving your agent a production-grade wallet with hardware-level security.
