API 符号和行情

上次更新时间： 2026年2月11日

符号

我们的 REST 和 WebSocket API 使用略有不同的符号来表示相同的底层市场（相同的货币对），因此有时需要在这不同版本之间来回转换符号。

REST 资产 (Assets) 和 资产对 (AssetPairs) 端点可用于检索所有可用货币和货币对（市场）的列表，以及每个市场所有可能的符号版本。

例如，将 REST 资产 (Assets) 端点调用为 https://api.kraken.com/0/public/Assets 将返回类似以下内容的响应：

Bash

{"aclass":"currency","altname":"REP","decimals":10,"display_decimals":5},"XTZ":
{"aclass":"currency","altname":"XTZ","decimals":8,"display_decimals":6},"XTZ.S":

{"aclass":"currency","altname":"XBT","decimals":10,"display_decimals":5},"XXDG":{"aclass":"currency","altname":"XDG","decimals":8,"display_decimals":2}...

其中列出了每种货币及其所有可能的符号，以及一些其他交易信息（特别是小数精度）。

同样，将 REST 资产对 (AssetPairs) 端点调用为 https://api.kraken.com/0/public/AssetPairs 将返回类似以下内容的响应：

Bash

其中列出了每个货币对（市场）及其所有可能的符号，以及各种额外的交易信息（价格/交易量精度、可用杠杆、最小订单规模等）。

行情

行情是单个货币对当前市场价格的报告，包括以下所有信息：

•
最新成交价格
•
最新成交量
•
最佳（最高）买入价
•
最佳买入价的可用交易量
•
最佳（最低）卖出价
•
最佳卖出价的可用交易量
•
其他交易信息（当日最高/最低价、交易数量、当日总交易量等）

REST 行情端点可用于检索单个货币对、一组货币对或 Kraken 当前提供的所有市场的行情数据。

例如，将行情端点调用为 https://api.kraken.com/0/public/Ticker?pair=xdgusd 将仅返回 Dogecoin/USD 市场的当前行情数据，例如：

Bash
