+[![Docs](https://img.shields.io/badge/Docs-uapis.cn-2EAE5D?style=flat-square)](https://uapis.cn/)
+
+> [!NOTE]
+> 所有接口的 Java 示例都可以在 [UApi](https://uapis.cn/docs/introduction) 的接口文档页面，向下滚动至 **快速启动** 区块后直接复制。
+
+## 快速开始
+
+```bash
+git clone https://github.com/AxT-Team/uapi-sdk-java.git
+cd uapi-sdk-java
+mvn -q package
+```
+
+```java
+import uapi.Client;
+import java.util.Map;
+
+public class Demo {
+    public static void main(String[] args) throws Exception {
+        var client = new Client("https://uapis.cn/api/v1", "");
+        var info = client.social().getSocialQqUserinfo(Map.of("qq", "10001"));
+        System.out.println(info);
+    }
+}
+```
+
+## 特性
+
+现在你不再需要反反复复的查阅文档了。
+
+只需在 IDE 中键入 `client.`，所有核心模块——如 `social()`、`game()`、`image()`——即刻同步展现。进一步输入即可直接定位到 `getSocialQqUserinfo` 这样的具体方法，其名称与文档的 `operationId` 严格保持一致，确保了开发过程的直观与高效。
+
+所有方法签名只接受真实且必需的参数。当你在构建请求时，IDE 会即时提示 `qq`、`username` 等键名，这彻底杜绝了在 `Map<String, Object>` 中因键名拼写错误而导致的运行时错误。
+
+针对 401、404、429 等标准 HTTP 响应，SDK 已将其统一映射为具名的异常类型（`UapiException.Unauthorized`、`UapiException.NotFound`、`UapiException.ServiceBusy` 等）。这些异常均附带 `status`、`code`、`details` 等关键上下文信息，确保你在日志中能第一时间准确、快速地诊断问题。
+
+基础域名、请求超时和 `User-Agent` 已预设为合理的默认值。但你完全拥有控制权，可以通过 `new Client(baseUrl, token)` 结合 OkHttp 自定义拦截器，灵活覆盖 Token、BaseURL 等配置。
+
+如果你需要查看字段细节或内部逻辑，仓库中的 `./internal` 目录同步保留了由 `openapi-generator` 生成的完整结构体，随时可供参考。

+# OpenAPI Generator Ignore
+# Generated by openapi-generator https://github.com/openapitools/openapi-generator
+
+# Use this file to prevent files from being overwritten by the generator.
+# The patterns follow closely to .gitignore or .dockerignore.
+
+# As an example, the C# client generator defines ApiClient.cs.
+# You can make changes and tell OpenAPI Generator to ignore just this file by uncommenting the following line:
+#ApiClient.cs
+
+# You can match any string of characters against a directory, file or extension with a single asterisk (*):
+#foo/*/qux
+# The above matches foo/bar/qux and foo/baz/qux, but not foo/bar/baz/qux
+
+# You can recursively match patterns against a directory, file or extension with a double asterisk (**):
+#foo/**/qux
+# This matches foo/bar/qux, foo/baz/qux, and foo/bar/baz/qux
+
+# You can also negate patterns with an exclamation (!).
+# For example, you can ignore all files in a docs folder with the file extension .md:
+#docs/*.md
+# Then explicitly reverse the ignore rule for a single file:
+#!docs/README.md
