How this service works
Wallet balances on Base or Ethereum in one call: native ETH plus WETH, USDC, USDT, DAI and cbBTC/WBTC (and optionally any extra ERC-20), with approximate USD value from Chainlink oracles.
Output
Returns a JSON object with the wallet address, chosen network, a list of token balances (each with asset name, contract address or null for native ETH, quantity, and approximate USD value), total portfolio USD value, and a block explorer URL for the address.
Example use cases
Pre-payment liquidity check
“Before I send the invoice, can you check if wallet 0xAbC123...456 on Ethereum has at least $500 in USDC or USDT right now?”
DeFi portfolio snapshot
“Give me a full balance breakdown — ETH, WETH, USDC, USDT, DAI, and WBTC — for my wallet 0xDef789...012 on Base, with the USD value of each token.”
Multi-token treasury audit
“I need to audit our treasury wallet 0x111aaa...bbb on Ethereum — show me all the major token balances and total USD value so I can update our finance spreadsheet.”
Technical details
Endpoint
POSThttps://api.vextorium.com/saldos-wallet-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call multi-token balance snapshot for a wallet on Base or Ethereum, especially when you want USD valuations alongside raw balances. It is ideal over single-token RPC calls when you need ETH plus all major stablecoins and wrapped BTC in one response. Prefer it over block explorer APIs when you need Chainlink-priced USD estimates without building your own price-feed logic.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported network value (not 'base' or 'ethereum') returns a validation error
- Chainlink oracle price unavailable for a token may result in null or zero USD value
- Invalid optional ERC-20 contract address may return null balance or contract read error
- Network timeout or RPC node unavailability causes a service error
