Questions

Is a route a guaranteed profit?
No. A route is a measured price difference at one moment. Spreads close, transfers take time and fills can differ. Check every route before acting on it.
How do you avoid phantom spreads?
A route is shown only after it has held for a while, when both quotes are close in time and there is executable size behind the price. Routes blocked by a known obstacle are left out.
How fresh is the data on each plan?
BASIC: 15-minute delay; PRO: 60-second delay; ULTRA: 15-second delay; MEGA: real time.
How far back can I query?
BASIC: no history; PRO: no history; ULTRA: 7 days of history; MEGA: 30 days of history. History is a rolling window counted from now; one request covers at most 24 hours.

18 exchange sources: spot and 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.
