}Builder fills
Every fill routed through one builder code, whatever the user, in Hyperliquid’s fill shape plus twapId, cloid, builderFee and builder.
Rows come newest first: limit keeps the newest fills of the window, and startTime is only a lower bound (it does not make the result start at startTime). There is no cursor: to go further back, narrow the window with endTime.
Rows do not carry the trader’s address. For per-user attribution, use builderOrderUpdates, which adds user and cursor paging.
Coverage: fills from at least July 2026 are returned. The newest fill is typically about a minute old.
