fix(api): use dynamic baseUrl instead of hardcoded localhost

Replace hardcoded 'http://127.0.0.1:8080' with dynamic info.baseUrl
to support configurable API endpoints.

This allows the ModelAPI to work with different base URLs configured
in the info object rather than being locked to localhost.

将硬编码的 'http://127.0.0.1:8080' 替换为动态的 info.baseUrl，
以支持可配置的 API 端点。

这使得 ModelAPI 能够使用 info 对象中配置的不同基础 URL，
而不是锁定到本地主机。
