How this service works
Live balance of a wallet: native coin plus up to 20 ERC-20 tokens you choose (USDC/USDT by default) in one call. Works on Base, Ethereum, Arbitrum, Optimism, Polygon, BNB Chain, Avalanche, Gnosis, Linea, Scroll, Sonic and Unichain.
Output
A JSON object containing the chain name, native coin ticker, native coin balance as a decimal number, the wallet address, and an array of requested ERC-20 tokens each with their contract address, symbol, human-readable balance, and raw balance string.
Example use cases
DeFi portfolio tracker balance check
“Fetch the current native coin and USDC/USDT balances for wallet 0xb9f06D2734B7E9D7b21B64C4D8b95bd774b71aCf on Arbitrum so I can update my portfolio dashboard.”
Multi-token wallet audit on Polygon
“Get the live balances for wallet 0xb9f06D2734B7E9D7b21B64C4D8b95bd774b71aCf on Polygon, including USDC, USDT, and these three token contracts: 0xabc..., 0xdef..., 0x123....”
On-chain payment verification
“Check whether wallet 0xb9f06D2734B7E9D7b21B64C4D8b95bd774b71aCf on Optimism currently holds at least 100 USDC — fetch its live USDC balance for me.”
Technical details
Endpoint
POSThttps://api.vextorium.com/evm-saldos-vivos-pago?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a combined native coin and multi-ERC-20 token balance snapshot for a single wallet address across any of 12 supported EVM chains in one low-cost call, rather than making separate RPC calls per token or per chain. It is especially useful for portfolio monitoring, payment verification, or DeFi agent workflows needing real-time balance data without running your own node infrastructure.
Side effects
- Invalid or malformed wallet address returns an error
- Unsupported chain name outside the 12 supported chains causes rejection
- Token contract address not found or non-ERC-20 address may return zero or null balance
- More than 20 tokens requested may be truncated or rejected
- Network RPC unavailability may cause a timeout or empty response
- Payment of 0.003 USDC not provided or rejected via x402 results in 402 response
