This is idempotent - calling DELETE when no partner fee exists returns the current state without error.
curl -s -X DELETE "https://trade.predexon.com/api/fees/policy?venue=polymarket" \
-H "x-api-key: YOUR_API_KEY"
{
"venue": "polymarket",
"enabled": true,
"platformFeeBps": 0,
"partnerFeeBps": 0,
"partnerTreasuryAddress": null,
"totalFeeBps": 0
}
