     "name": "MyAgent",
     "context": "You are a Starknet monitoring agent...",
     "interval": 60000,
     "chat_id": "your_discord_channel_id",
     "allowed_actions": ["get_balance", "get_block_number"],
     "prompt": "Monitor ETH balance and alert if it drops below 1 ETH..."
   }
   

Library Mode

import { StarknetAgent } from 'starknet-agent-kit';

const agent = new StarknetAgent({
  provider: new RpcProvider({ nodeUrl: process.env.STARKNET_RPC_URL }),
  accountPrivateKey: process.env.STARKNET_PRIVATE_KEY,
  accountPublicKey: process.env.STARKNET_PUBLIC_ADDRESS,
  aiModel: process.env.AI_MODEL,
  aiProvider: process.env.AI_PROVIDER,
  aiProviderApiKey: process.env.AI_PROVIDER_API_KEY,
  signature: 'key',
});

const response = await agent.execute("What's my ETH balance?");
