Important Notes

• Kalshi fees are NOT automatic — the agent must call this endpoint after every successful trade
• If charge_kalshi_fee() fails, the order itself is NOT affected (already submitted on-chain)
• The fee amount is calculated from the order’s filledAmount (if available) or orderAmount
• Agent commission (10% of fee) is calculated and tracked automatically
• Use get_fee_status(txSignature, venue="kalshi") to verify fee was collected
