How this service works
Look up any wallet's token holdings with live USD values: every ERC-20 position with amount, price, USD value and portfolio %, total portfolio value, top-position concentration, and spam/unpriced filtering. The 'bagcheck' call for copy-trading, risk, research and portfolio agents. Across Base, Ethereum, Optimism, Arbitrum, Polygon. Free upstream (Blockscout).
Output
Returns a JSON object containing an array of token holdings (each with symbol and USD value), total portfolio USD value, number of tokens held, and the top position by percentage allocation.
Example use cases
Example prompt
“What tokens does wallet 0x1234...abcd hold on Base, and what's the total USD value of the portfolio?”
