latestOpenAPI 3.0.32026-07-2613529376.3 KBQuery Market Fees
Returns the account's default spot and futures maker and taker fees, plus any custom per-market overrides.
The maker and taker fields represent default spot trading fees. The futures_maker and futures_taker fields represent default futures trading fees. The custom_fee object lists per-market overrides, keyed by market name.
The system calculates the effective futures fee as the lower value between the user-specific custom fee and the market-specific fee.
When the market fee is lower than the assigned custom fee, the system returns the market fee.
Example: If the custom futures taker fee equals 0.026 and the market fee equals 0.02, the response returns 0.02.
