One API. Every exchange.
Unified REST and WebSocket API for trading spot and futures across 20+ exchanges. Agency or principal model — your keys stay encrypted, orders get routed.
WHY CADENZA
The exchange integration you stop thinking about.
Cadenza normalizes order types, data formats, and error handling across venues. You focus on strategy — we handle the plumbing.
Write once, trade everywhere
A single API call routes to 20+ exchanges — spot and futures. No more maintaining individual integrations that break with every exchange update.
Real-time streaming
WebSocket streams powered by Centrifugo deliver order book updates, trades, and fills in real time. REST endpoints for account management and order placement.
One account view
Aggregate balances, positions, and P&L across all connected exchanges. No more manual reconciliation.
TRADING MODELS
Two models. One API.
Trade directly through your own exchange accounts, or create sub-accounts for managed portfolios.
