A structured breakdown of all token holdings in the specified wallet address, including token names, symbols, quantities, and potentially USD values or chain-specific metadata for assets held on Base and other supported chains.
Example use cases
DeFi portfolio snapshot for a wallet
“Fetch the complete token portfolio for 0x742d35Cc6634C0532925a3b8D4C9B8e5a1f9cAbD and list every asset it holds with balances.”
Automated wallet monitoring in an agent pipeline
“Every time my agent runs, check the portfolio of wallet 0xDeadBeef... and alert me if any token balance drops below what it was last run.”
Investor due diligence on a wallet
“I'm looking at this DAO treasury wallet — can you pull up its full portfolio so I can see what tokens it's holding and roughly how diversified it is?”
Technical details
Endpoint
POSThttps://x402.freeq.one/tools/wallet_portfolioWhen to prefer
Choose this endpoint when you need a fast, pay-per-call wallet portfolio lookup without committing to a subscription. Especially useful in agentic pipelines that only occasionally need portfolio data, or when building on Base with x402 micropayment infrastructure already in place. Prefer over free alternatives when you need reliable uptime backed by Coinbase CDP infrastructure.
Side effects
- Invalid wallet address format returns an error
- Wallet address with no on-chain activity returns empty portfolio
- Payment failure via x402 if insufficient USDC balance causes request rejection
- Unsupported chain or token may be omitted from results
- Network timeout if blockchain RPC is slow
