## Overview
-Sub2API is an AI API gateway platform designed to distribute and manage API quotas from AI product subscriptions (like Claude Code $200/month). Users can access upstream AI services through platform-generated API Keys, while the platform handles authentication, billing, load balancing, and request forwarding.

+## Nginx Reverse Proxy Note
-- Dependency Security: `docs/dependency-security.md`
-- Admin Payment Integration API: `docs/ADMIN_PAYMENT_INTEGRATION_API.md`
+When using Nginx as a reverse proxy for Sub2API (or CRS) with Codex CLI, add the following to the `http` block in your Nginx configuration:
+
+```nginx
+underscores_in_headers on;
+```
+
+Nginx drops headers containing underscores by default (e.g. `session_id`), which breaks sticky session routing in multi-account setups.

-## 文档
+## Nginx 反向代理注意事项
-- 依赖安全:`docs/dependency-security.md`
+通过 Nginx 反向代理 Sub2API(或 CRS 服务)并搭配 Codex CLI 使用时,需要在 Nginx 配置的 `http` 块中添加:
+
+```nginx
+underscores_in_headers on;
+```
+
+Nginx 默认会丢弃名称中含下划线的请求头(如 `session_id`),这会导致多账号环境下的粘性会话功能失效。
---
-## OpenAI Responses 兼容注意事项
-
-- 当请求包含 `function_call_output` 时,需要携带 `previous_response_id`,或在 `input` 中包含带 `call_id` 的 `tool_call`/`function_call`,或带非空 `id` 且与 `function_call_output.call_id` 匹配的 `item_reference`。
-- 若依赖上游历史记录,网关会强制 `store=true` 并需要复用 `previous_response_id`,以避免出现 “No tool call found for function call output” 错误。
