In short: you want numbers from right now, not from yesterday: what a perpetual (a futures contract with no end date) pays, who just got liquidated, or what an option costs. These three tools read the newest data instead of a daily history, so asking twice can give different answers. The perpetual figure is a sample a few minutes old, and the answer says how old. The Hyperliquid liquidation feed names the address behind each forced close. Three tools read the newest data instead of a daily history: what a perpetual is paying at its latest sample, who has just been liquidated, and what an option costs right now. Every other research tool reads recorded history, so the same question asked twice gives the same answer. These three cannot work that way, and each of them says so.

​
What a perpetual pays right now

Tool: get_hyperliquid It returns annualised funding, open interest, and mark against oracle, from the latest sample a watcher took. The watcher samples every few minutes. The answer leads with the age of the sample. When the sample is more than ten minutes old, the answer says STALE and says the figure is not the rate now. A reader who sees an hour-old figure presented as live would trade on it, so the age comes first. Funding and open interest walks recorded days and answers whether a carry has been worth having. This answers what it paid at the last sample, which is the question somebody asks before opening one.
Hyperliquid settles funding hourly: 24 intervals in a day, not 3. An hourly rate read as an 8-hourly one is wrong by a factor of eight, in the direction that makes a carry look far better than it is.
The venue publishes open interest only as it is now and keeps no history of it, so that part of the stream records forward only and begins when the watcher began. It cannot be backfilled, and the answer does not claim otherwise.

​
Who has just been liquidated

Tool: get_liquidations It returns forced closes as they happened, each with the address it happened to. No centralised venue publishes that. Liquidation, not price, is what stops a leveraged hedge hedging. A cluster of forced closes at a level is the risk a perpetual carries that an option does not: an option cannot be liquidated, and that difference is most of the reason to pay for one.
The two liquidation streams are never merged. The centralised one is an hourly aggregate and cannot name a trader. The Hyperliquid one is one row per event and can. Merging them would drop the detail on one side and invent it on the other.
See liquidations for the depth of each.

​
What an option costs right now

Tool: price_options_live It reads the real Deribit book, not a daily snapshot. See pricing against the live book. A price somebody is about to trade on cannot come from yesterday’s close, so here an answer that changes between calls is correct.
