-### gzip Compression Support
-
-NodePass API supports gzip compression to significantly reduce network traffic and improve response performance:
-
-- Automatic Activation: Compression is automatically enabled when client sends `Accept-Encoding: gzip` request header
-- Universal Support: All API endpoint responses support gzip compression, including JSON data, HTML documents, and SSE event streams
-- Transparent Usage: Modern browsers and HTTP client libraries automatically handle compression and decompression
-- Performance Improvement: Typical JSON response compression ratios reach 60-80%, significantly reducing bandwidth usage

-### gzip 压缩支持
-
-NodePass API 支持 gzip 压缩，可显著减少网络流量并提高响应性能：
-
-- 自动启用：当客户端发送 `Accept-Encoding: gzip` 请求头时自动启用压缩
-- 全面支持：所有 API 端点响应内容均支持 gzip 压缩，包括 JSON 数据、HTML 文档和 SSE 事件流
-- 透明使用：现代浏览器和 HTTP 客户端库自动处理压缩和解压缩
-- 性能提升：典型的 JSON 响应压缩率可达 60-80%，显著降低带宽使用
