API 符號和行情

上次更新時間： 2026年2月11日

符號

我們的 REST 和 WebSocket API 使用略有不同的符號來表示相同的基礎市場（相同的貨幣對），因此有時需要在不同版本之間來回轉換符號。

REST Assets 和 AssetPairs 端點可用於檢索所有可用貨幣和貨幣對（市場）的列表，以及每個市場所有可能的符號版本。

例如，將 REST Assets 端點呼叫為 https://api.kraken.com/0/public/Assets 將返回類似以下的響應：

Bash

{"error":[],"result":{...{"aclass":"currency","altname":"SRM","decimals":8,"display_decimals":5},"STORJ":
{"aclass":"currency","altname":"STORJ","decimals":10,"display_decimals":5},"SUSHI":

{"aclass":"currency","altname":"WAVES","decimals":10,"display_decimals":5},"WBTC":
{"aclass":"currency","altname":"WBTC","decimals":10,"display_decimals":5},"XBT.M":
{"aclass":"currency","altname":"XBT.M","decimals":10,"display_decimals":8},"XETC":
{"aclass":"currency","altname":"ETC","decimals":10,"display_decimals":5},"XETH":
{"aclass":"currency","altname":"ETH","decimals":10,"display_decimals":5},"XLTC":
{"aclass":"currency","altname":"LTC","decimals":10,"display_decimals":5},"XMLN":
{"aclass":"currency","altname":"MLN","decimals":10,"display_decimals":5},"XREP":
{"aclass":"currency","altname":"REP","decimals":10,"display_decimals":5},"XTZ":
{"aclass":"currency","altname":"XTZ","decimals":8,"display_decimals":6},"XTZ.S":
{"aclass":"currency","altname":"XTZ.S","decimals":8,"display_decimals":6},"XXBT":
{"aclass":"currency","altname":"XBT","decimals":10,"display_decimals":5},"XXDG":{"aclass":"currency","altname":"XDG","decimals":8,"display_decimals":2}...

其中列出了每種貨幣及其所有可能的符號，以及一些其他交易資訊（特別是小數精度）。

同樣，將 REST AssetPairs 端點呼叫為 https://api.kraken.com/0/public/AssetPairs 將返回類似以下的響應：

Bash

其中列出了每個貨幣對（市場）及其所有可能的符號，以及各種額外的交易資訊（價格/交易量精度、可用槓桿、最小訂單規模等）。

行情

Ticker 是單一貨幣對當前市場價格的報告，包含以下所有資訊：

•
最新成交價格
•
最新成交量
•
最佳（最高）買入價
•
最佳買入價的可用交易量
•
最佳（最低）賣出價
•
最佳賣出價的可用交易量
•
額外交易資訊（當日最高/最低價、交易數量、當日總交易量等）

REST Ticker 端點可用於檢索單一貨幣對、一組貨幣對或 Kraken 目前提供的所有市場的行情數據。

例如，將 Ticker 端點呼叫為 https://api.kraken.com/0/public/Ticker?pair=xdgusd 將僅返回 Dogecoin/USD 市場的當前行情數據，例如：

Bash
