# Introduction

### About

Cube is a hybrid exchange built from first principles for the future of digital and traditional asset trading. At it's core, a low-latency matching engine powers trading at 200'000 operations per second with 200µs latency, and a decentralized settlement layer powers a non-custodial peer-to-peer settlement that ensures the safety of your assets.

### Overview

This documentation covers a large part of the Cube API, and is roughly organized into the following:

* [Exchange Info](/cube-api/exchange-info.md): Information about the exchange, such as assets, markets, account management, and more.
* [Market Data](/cube-api/market-data/rest-api.md): Market data, including level 3 (order by order) book data, trade summaries, and more.
* [Order Entry](/cube-api/order-entry/rest-api.md): Trading and order management.
* [Perpetual Futures](/cube-api/perpetual-futures.md): Information about our perpetual futures contracts, including contract specifications, margin requirements, funding, settlement, and liquidation.
* [Fees](/cube-api/fees/cube-fees.md): Information about fees on Cube.

#### Connectivity

* **REST**: For market data snapshots and order entry.
* **Websocket**: For realtime market data and trading.
* **TCP FIX and UDP Multicast**: Out lowest latency connectivity. Reach out for more information.
