More Details Connect to Claude

Empower your AI agent to orchestrate your entire web3 research and blockchain auditing workflow with Alchemy, the comprehensive platform for decentralized data. By connecting Alchemy to your agent, you transform complex RPC querying into a natural conversation. Your agent can instantly retrieve wallet balances, audit NFT ownership, and query transaction receipts without you ever touching a block explorer. Whether you are conducting investment research or monitoring digital assets, your agent acts as a real-time blockchain analyst, ensuring your data is always precise and up-to-the-minute.

What you can do

  • Wallet Auditing — Retrieve high-resolution balances for any Ethereum or compatible address, including native and ERC-20 tokens.
  • NFT Oversight — Audit the NFT collection for specific owners to maintain a clear view of digital asset distribution and metadata.
  • Transaction Intelligence — Query real-time transaction receipts to understand the status and outcome of blockchain events instantly.
  • Network Discovery — Retrieve the latest block numbers to assist in regional and temporal blockchain planning.
  • Operational Monitoring — Check API status to ensure your web3 research workflow is always operational across supported networks.

  2. Enter your Alchemy API Key and select your target Network
  3. Start managing your blockchain intelligence through Claude, Cursor, or any MCP-compatible client

I've retrieved the balance for that address! The current balance is 1.5 ETH (represented in wei). I can assist you with the ERC-20 token balances for this wallet if you'd like.
