How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
Returns a JSON object containing the wallet address, blockchain network, timestamp, a list of token holdings (with balances and values), the native token balance, total token count, and the total portfolio value in USD.
Example use cases
DeFi portfolio check for a trader
“Can you pull up the full token portfolio for wallet 0xAbCd1234...5678 on Ethereum and tell me the total USD value and what tokens it holds?”
Monitor a whale wallet's holdings
“What's the current portfolio composition and total value of this whale address 0x3f5CE5FBFe3E9af3971dD833D26bA9b5C936f0bE on Base?”
Verify a user's on-chain assets before a transaction
“Before we proceed, can you check what tokens and native balance wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 currently has on Ethereum?”
Technical details
Endpoint
GEThttps://klymax402.com/api/wallet-portfolio/api/portfolioWhen to prefer
Choose this endpoint when you need a fast, pay-per-call portfolio snapshot for any wallet on Base or Ethereum without managing API keys. It is ideal for lightweight agent workflows that occasionally need on-chain portfolio data without subscribing to a full blockchain data provider. Prefer alternatives if you need historical portfolio data, NFT holdings, or support for chains beyond Base and Ethereum.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported chain value returns a validation error
- Empty wallet with no tokens returns an empty token array
- Network timeout or upstream data provider outage causes a 5xx error
- Payment failure (insufficient USDC or x402 rejection) blocks the request
