Each blockchain network supported by Finrock uses native tokens (e.g., ETH on Ethereum, BNB on BNB Chain) to pay on-chain transaction fees. This endpoint lets you query the real-time balance of the gas tank for a specific asset, so you can proactively top it up before withdrawals or sweeps start failing due to insufficient fee reserves.
