How this service works
ETH and USDC balance of any address on Base, read live from the chain (eth_getBalance + USDC balanceOf) at request time. Pass ?address=0x... . Returns raw and decimal values plus the block number the read was made at. No third-party API, no cache.
Output
Returns the ETH balance (in both raw wei and human-readable decimal) and USDC balance (in both raw units and decimal), along with the block number at which the on-chain read was made. No caching — values reflect the live chain state at request time.
Example use cases
DeFi bot pre-trade balance check
“Before executing this trade, check the live ETH and USDC balances of 0xAbCdEf1234567890AbCdEf1234567890AbCdEf12 on Base so I know if there's enough to cover the swap.”
Portfolio tracker wallet snapshot
“Pull the current ETH and USDC balances for 0xDeAdBeEf00000000000000000000000000000001 on Base and tell me what block the data was read from.”
Payment confirmation after transfer
“I just sent USDC to 0x9999888877776666555544443333222211110000 on Base — can you check if the balance has updated on-chain yet?”
Technical details
Endpoint
GEThttps://oraclepost.higgsfield.app/api/premium/balanceWhen to prefer
Choose this endpoint when you need a trustless, uncached, live on-chain balance read for both ETH and USDC on Base in a single call. Ideal when you cannot rely on third-party indexers or cached APIs and need the exact block-level snapshot. Prefer over cached alternatives when precision and freshness are critical, such as pre-trade checks or post-transfer confirmations.
Side effects
- Invalid or malformed address (not 0x-prefixed or wrong length) results in an error response
- Address not found on Base — returns zero balances rather than an error
- Node connectivity issues may cause transient failures or timeouts
- Payment failure (x402) if USDC payment of $0.02 is not provided or rejected
