Questions

Are liquidation totals complete?
Each venue is labelled. Two venues publish every liquidation; one publishes only the largest per symbol per second, so its totals are a lower bound.
How much history is there?
History accumulates from the day collection started. Every history response carries history_from_ts, the first stored timestamp.
How fresh is the data on each plan?
BASIC: 15-minute delay; PRO: 60-second delay; ULTRA: 15-second delay; MEGA: 5-second delay.
How far back can I query?
BASIC: no history; PRO: 7 days of history; ULTRA: 30 days of history; MEGA: 30 days of history. History is a rolling window counted from now; one request covers at most 24 hours.

9 exchange sources: perpetual futures. Derived events and aggregates only: no raw order books, no trade tape, no detection rules. History is a rolling window up to 30 days back. The licence covers use inside your own application, bot, dashboard or research. Redistributing the data as a feed, an API or a dataset, or re-hosting it as an MCP server, is not allowed.
