    高性能行情数据服务，支持 A股、ETF、美股、港股。

    ## 认证方式

    所有接口需要通过 `x-api-key` 请求头传递 API Key 进行认证。

    ## 速率限制

    根据 API Key 配置的权限，可能会有请求频率和配额限制。

    ## 批量查询

    部分接口同时支持 GET 和 POST 方法：
    - **GET**: 通过 URL 参数传递，适合少量数据
    - **POST**: 通过 JSON Body 传递，适合大批量查询，不受 URL 长度限制

    ## K线周期

    支持的周期：1m, 5m, 10m, 15m, 30m, 60m, 1d, 1w, 1M, 1Q, 1Y
    - 日内周期(5m/15m/30m/60m)从1m数据聚合
    - 周线(1w)/月线(1M)/季线(1Q)/年线(1Y)从日线聚合
    - intraday 接口当前为 Beta 版本
