EndpointLarge-trade tape: taker prints at or above the tape threshold ($250k for BTC / ETH, $50k otherwise; one print = the fills of one taker order at one timestamp), newest first in order of arrival (id; an exchange print can arrive after a later Hyperliquid one), with the Hyperliquid taker address (public on-chain state) and whether it is a tracked whale. Bots poll forward with after. Free keys: BTC, ETH and HYPE, last 24 hours. Licence review: raw rows of Binance and Bybit (single liquidations, prints, order books, tickers, funding and ratios per exchange, exchange candles) are not redistributed through the API while the review of their terms is pending. Asking for such a venue answers 403 source_restricted, and meta.restricted lists the withheld venues. Aggregates (sums over venues, our own figures) stay.
