How this service works
Multi-chain blockchain data API. 7 chains. x402 pay-per-call with USDC on Base.
Output
Returns the native token balance held by the specified wallet address on the requested blockchain chain, expressed as a numeric amount in the chain's native token unit.
Example use cases
Pre-transaction wallet funding check
“Before I send this transaction, can you check whether wallet 0x1234567890abcdef1234567890abcdef12345678 has enough balance on Polygon?”
Portfolio balance snapshot across chains
“Look up the native token balance for 0xDeAdBeEf0000000000000000000000000000dEaD on Base — I want to see how much ETH equivalent is sitting there.”
Monitoring a smart contract treasury
“Can you pull the current native balance for address 0xAaBbCcDd11223344AaBbCcDd11223344AaBbCcDd on Arbitrum so I can track how much is left in the treasury?”
Technical details
Endpoint
POSThttps://chain.gpuops.io/v1/balanceWhen to prefer
Choose this endpoint when you need a quick, pay-per-call native token balance lookup across any of 7 supported blockchain networks without needing to maintain a node or subscription. It is ideal for agents that need occasional on-chain reads at very low cost ($0.001 per call) and want multi-chain support in a single API surface. Prefer alternatives if you need ERC-20 token balances, transaction history, or high-volume batch queries.
Side effects
- Invalid or malformed wallet address returns an error response
- Unsupported chain identifier causes a rejection or empty result
- Payment failure via x402/USDC results in a 402 response and no data returned
- Network congestion or node unavailability may cause timeouts
- Address with no activity may return zero balance without error
