Large-trade tape

Large-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.

Description

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.

Who can call it

Parameters

Parameters of /tape
Parameter	Description
`coin`string	Only this coin (optional; free keys: BTC, ETH or HYPE, default all three).
`venue`string	hyperliquid \| binance \| bybit (optional).one of hyperliquid, binance, bybit
`side`string	buy \| sell = side of the taker (optional).one of buy, sell
`minUsd`number	Minimum print size in USD on top of the tape threshold, default 0.≥ 0 · default 0
`sinceMinutes`integer	Look-back window in minutes, default 60, clamped to the plan history (free key 60).≥ 1 · default 60
`from`string	Window start (ISO 8601, inclusive); replaces sinceMinutes. Clamped to the plan history (meta.warnings says so).ISO 8601, e.g. 2026-10-23T12:00:00Z
`to`string	Window end (ISO 8601, exclusive; default now): prints before it.ISO 8601, e.g. 2026-10-23T12:00:00Z
`after`integer	Forward polling: only prints with an id above this one, oldest first (pass meta.nextAfter of the previous poll; without from / sinceMinutes the window is the plan history). Cannot be combined with cursor.≥ 0
`limit`integer	Number of items, default 100, clamped to 1–1000.1–1000 · default 100
`cursor`string	Next page: the value of meta.nextCursor from the previous response (keep the other parameters unchanged). Cursors are signed: an edited cursor answers 400; paging stops at the plan history.
`fields`string	Comma-separated fields of every item to return, e.g. ts,coin,side,px,usd (case-insensitive). All other fields are left out, so large lists get much smaller; an unknown name answers 400 with the list of fields. Default: every field.
`format`string	json (default: the { data, meta } envelope) \| csv (the rows with a header line; nested values as JSON text) \| ndjson (one JSON object per row and line). csv and ndjson carry the meta block in headers: Link rel="next" and X-Blockmetric-Next-Cursor (next page), X-Blockmetric-Next-After (forward polling), X-Blockmetric-Updated-At, X-Blockmetric-Warnings, X-Blockmetric-License. Errors stay JSON.one of json, csv, ndjson · default json
