How this service works
Run a low-cost wallet balance lookup for native ETH and official USDC on Base, Ethereum, or Arbitrum, with an estimated ETH USD value. This is not a complete token or NFT portfolio.
Output
Returns a JSON object with the queried wallet address, an array of held assets each with symbol, balance, current price in USD, and value in USD, plus a total net_worth_usd field summing all asset values.
Example use cases
Due diligence on a counterparty wallet
“Before I finalize this deal, can you check the on-chain portfolio of 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 and tell me what tokens they hold and their total net worth in USD?”
Monitor personal crypto net worth
“What's the current total USD value of my wallet vitalik.eth, and what tokens am I holding across all chains?”
Verify investor wallet holdings
“Can you look up the wallet 0xAbCd1234...5678 and show me a full breakdown of their token balances with current USD prices so I can verify their claimed holdings?”
Technical details
Endpoint
GEThttps://ai-data-marketplace-1042299154756.us-central1.run.app/api/v1/wallet_portfolioWhen to prefer
Choose this endpoint when you need a quick, pay-per-use on-chain wallet portfolio snapshot with USD valuations across multiple EVM chains, especially within an agent workflow that already uses x402 USDC micropayment settlement. Prefer it over free block explorers when you need structured, machine-readable JSON output with pre-computed USD values rather than raw block data.
Side effects
- Invalid or malformed wallet address returns an error response
- ENS resolution fails if the name is unregistered or DNS lookup is unavailable
- Unsupported chain parameter returns empty or error
- Wallet with zero on-chain activity may return empty assets array
- Rate limiting or x402 payment failure results in a 402 response requiring USDC settlement
