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. ## OpenAPI ````yaml /live-data/openapi-rest.json post /info#builderFills openapi: 3.0.3 info: title: 'Hypedexer API: Live Data (REST)' version: 0.1.0 description: >- REST API for real-time Hyperliquid market data served from our own Hyperliquid nodes.
