I'm seeing a large discrepancy between onchain volume and volumeClob in the gamma api. Especially for markets which closed between Sep 2025 and Mar 2026

Hi, I thought that the March 31 2026 fees were implemented in NEW markets only - but in the Gamma API I see existing markets with fee info. Is this wrong or am I missing something? Example: ``` curl -s --request GET --url https://gamma-api.polymarket.com/markets/1421690 | jq '{question: .question, startDate: .startDate, feeType: .feeType, fees: .feeSchedule}' { "question": "Will Mohamed Diomande record the most red cards in 2025-26 UEFA Europa League?", "startDate": "2026-02-24T23:40:06.160039Z", "feeType": "sports_fees_v2", "fees": { "exponent": 1, "rate": 0.03, "takerOnly": true, "rebateRate": 0.25 } } ```

That is likely a geopolitics market which is exempted from fees.

`curl --request GET --url https://gamma-api.polymarket.com/markets/1921174` has feeType:null despite not being a geopolitics/world market. Many such examples.

If fee_type is NULL in the markets api, does that mean there are no fees irrespective of the category?
