# Overview

> Introduction to the Ekiden WebSocket API.

The Ekiden WebSocket API enables real-time, event-driven communication over persistent WebSocket connections. It complements the REST API by streaming market data and account events with minimal latency.

Ekiden provides two WebSocket endpoints:

* **Public** — streams publicly available market data, including order books, trades, tickers, candlesticks and other market events.
* **Private** — streams authenticated account events, including order updates, executions, positions, balances, transfers, and other account-related events.

The typical connection flow is:

1. Connect to the appropriate WebSocket endpoint.
2. Authenticate (private endpoint only).
3. Subscribe to one or more topics.
4. Receive real-time event updates.
5. Keep the connection alive using Ping/Pong messages.

The following pages explain how to establish a connection, authenticate, and subscribe to topics.

For complete channel definitions, message schemas, payload formats, and interactive examples, see the [**WebSocket Reference Public**](./api-reference/websockets/public) and [**WebSocket Reference Private**](./api-reference/websockets/private).
