# 交易所

一家永续合约交易所：交易什么、如何定价、如何管理风险。

Nexus Exchange 是一个永续合约交易所：采用中央限价订单簿，配备原生的撮合引擎、风险系统和预言机，以 [USDX](/exchange/zh-cn/overview/usdx.md) 计价并作为保证金。USDX 尚未上线：测试网市场使用从水龙头领取的合成 USDX 作为保证金，这些 USDX 不具有任何现实价值。

> **API 基础 URL 已变更**。交易所 API 已从 `https://exchange.nexus.xyz/api/exchange` 迁移至 `https://api.testnet.nexus.xyz/v1`。请将您的客户端指向新的基础 URL。在2026-09-28，`GET /markets/summary` 在旧基础 URL 上返回 HTTP 500，在新基础 URL 上返回 HTTP 200。请求签名方式不变：签名的是不含基础前缀的路径，因此 `/v1/markets` 签名 `/markets`，与 `/api/exchange/markets` 的做法相同。请参阅 [API 与速率限制](/exchange/zh-cn/apis-and-rates/apis-and-rates.md)。

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.nexus.xyz/exchange/zh-cn/readme.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
