能否加个一键markdown转wx_markdown的API接口

如题，就比如 提供markdown，然后通过API将生成后的wx_markdown返回，API的参数可以设置样式等。 因为我想通过AI自主生成markdown再通过API生成wx_markdown一步到位，然后再通过微信API直接设置到草稿箱。

Start by locating the existing Markdown-to-WeChat rendering or export entry points and any current API surface. Define how Markdown input, style options, and wx_markdown output should be represented, then verify the result can support the stated WeChat draft workflow. The issue does not name files, tests, or an existing endpoint, so the interface and scope need maintainer agreement first.
