How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
A JSON object containing the wallet address, a list of tokens with their symbols, raw balances, and USD values, plus the total portfolio USD value and native ETH balance.
Example use cases
DeFi portfolio snapshot for a user
“Can you pull up the full token portfolio for the wallet address 0xAbCd1234...5678 and tell me the total USD value and what coins it holds?”
Onchain due diligence for a counterparty
“Before I send funds, can you check the wallet 0xDeAdBeEf...9999 and tell me what assets and balances it has onchain?”
Track treasury wallet holdings
“I want to monitor our DAO treasury at 0xTreasury...0001 — can you grab the current token balances and total USD value right now?”
Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/wallet-portfolio?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, no-account, pay-per-call lookup of a wallet's token holdings and total USD value on EVM-compatible chains. Prefer this over managed API services when you want micropayment-based access without API key setup, or when integrating into an agent that pays per query in USDC on Base.
Side effects
- Invalid or malformed wallet address returns an error response
- Address with no onchain activity may return empty token list
- Network timeouts or RPC unavailability may cause request failure
- Non-EVM or unsupported chain addresses will not return valid data
- Payment failure via x402 will block the request from being fulfilled
