How this service works
Wallet balance: native coin plus USDC/USDT/DAI, ENS name, on 5 chains. Balance of any wallet (0x address or .eth name) on ethereum, base, arbitrum, optimism or polygon: native coin, USDC, USDT and DAI, whether it is a contract, and its verified ENS name.
Output
Returns a JSON object with the wallet's native token symbol and balance, resolved 0x address, ENS name (if applicable), and a map of stablecoin balances (e.g. USDC amounts) held by that address on the specified chain.
Example use cases
Verify wallet funding before transaction
“Check if the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 has at least 0.5 ETH and any USDC on Base before I send that payment.”
Portfolio snapshot for ENS name
“What are the current native token and stablecoin balances for vitalik.eth across — start with Ethereum mainnet?”
Arbitrum wallet audit for DeFi app
“Pull the ETH and stablecoin balances for 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B on Arbitrum so I can see if they qualify for the airdrop.”
Technical details
Endpoint
GEThttps://sift.srv1996466.hstgr.cloud/v1/crypto/balance?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, pay-per-call balance check for any EVM-compatible wallet without maintaining your own RPC infrastructure. It supports ENS resolution out of the box and covers multiple chains (Ethereum, Base, Arbitrum, Optimism, Polygon). Prefer it over rolling your own Web3 calls when you want low-overhead, agent-friendly JSON output with transparent per-call USDC pricing via x402.
Side effects
- Invalid or malformed wallet address returns an error
- ENS name cannot be resolved (non-existent or unregistered)
- Unsupported chain name returns a validation error
- Network RPC unavailability causes timeout or 5xx error
- Payment fails (non-200) so no charge is incurred
