## yingce.payment/v1

支持 `validate_config`、`create_order`、`query_order`、`close_order`、`verify_notification` 和 `download_trade_bill`，统一返回 JSON 响应。

虎皮椒渠道协议全部封装在本插件内：下单 `POST /payment/do.html`（JSON），查单 `POST /payment/query.html`，异步通知为 form，成功应答 `success`。配置字段包括 `publicBaseUrl`、`appId`、`appSecret`、`gateway`、`checkoutMode`。没有独立关单和交易账单下载接口：未支付关单按查单结果本地关闭，对账账单返回 not found。

## Manifest 完整接口定义

以下 JSON 与插件包内实际 `manifest.json` 逐字段一致，覆盖插件身份、权限、配置、鉴权、参数、校验、创建、Agent、查询、取消、结果下载、响应和 Agent 响应映射。`documentation` 字段的值就是当前完整文档；为避免文档在自身内部无限递归，JSON 中仅用等义占位文本表示正文。
