Trading, data and accounts on one REST and WebSocket API. Anything the terminal does, your code can do.
Every engine change runs the single-fill benchmark before it ships.
<10µs
Book, trades, candles and your own fills, pushed as they happen.
One call clears every resting order, on its own budget.
Up to 39 orders in a batch cost one unit of rate limit.
Up to ten subaccounts, funded from the main one by transfer.
Every endpoint, with real requests and real responses on testnet. Copy the call as curl, TypeScript, Python or the command line.
The chart, the book and the ticket are drawn from the same endpoints your systems call. Trade it by hand here, then automate the exact same thing.
Create a key, point an SDK at testnet and send your first order.
