# CCSub

> Claude Code 超强平替 — AI API 中转平台，支持 Claude / GPT / Gemini 等主流模型，比 Anthropic 官方直连便宜最多 70%，充值 ¥1 = $1 USD 余额。

Last updated: 2026-05-24

CCSub is an AI API relay platform that gives developers unified access to Claude, GPT, Gemini, and other leading LLMs through Anthropic and OpenAI-compatible endpoints. It is designed as a drop-in replacement for `api.anthropic.com` and `api.openai.com` for tools like Claude Code, Cursor, Continue, Cline, Aider, and Codex CLI.

Compared to calling Anthropic or OpenAI directly, CCSub offers significantly lower effective pricing (¥1 = $1 USD of API balance, versus ~¥7 per $1 at official rates), full Prompt Caching support, and no per-account rate limits for paid users.

## Key Features

- **Drop-in replacement** — Works with Claude Code CLI, Cursor, Continue, Cline, Aider, Codex CLI, and any tool that speaks the Anthropic or OpenAI API format
- **Dual-protocol** — `https://www.ccsub.net` for Anthropic format, `https://www.ccsub.net/v1` for OpenAI-compatible
- **Models** — Claude Opus 4.8, Opus 4.6, Sonnet 4.6, Haiku 4.5; GPT-5, GPT-5 Codex; Gemini 3.5 Flash, Gemini 2.5 Pro, Gemini 2.5 Flash, Gemini 2.5 Flash Lite; full 1M context on supported models
- **Prompt Caching** — Full `cache_control` support on Anthropic protocol, Cache Read billed at 10% of Input price
- **Multi-tier routing** — Starter (0.7x), Pro (0.8x), Standard (1.5x), Business (2.5x), Enterprise / AWS Bedrock (3.6x), with automatic failover and group-based isolation
- **Low barrier to entry** — Pay as you go from ¥20, monthly plans from ¥99, free trial credits on signup
- **Domestic China payments** — WeChat Pay, Alipay, USDT, bank transfer
- **Invoicing** — VAT普票/专票 available for enterprise
- **Affiliate program** — 10-20% commission on referrals

## Pricing

Key point: CCSub treats `¥1 = $1 USD of API balance`, while Anthropic/OpenAI official rate is ~¥7 per $1. Combined with 0.7x–3.6x billing multiplier across groups, users typically pay 30–60% less than direct API usage.

| Plan | Price | Group | Multiplier | Best for |
|------|-------|-------|------------|----------|
| Starter (PAYGO) | ¥20 起 | starter | 0.7x | Trial / light GPT use |
| Claude Pro | PAYGO | pro | 0.8x | Budget Claude, 1M context |
| OpenAI Only | PAYGO | openai-only | 0.7x | Codex / GPT-5 agents |
| Claude Standard | PAYGO | claude-only | 1.5x | Lower cost Claude |
| Claude Business | PAYGO | business | 2.5x | Enterprise stability |
| Monthly Standard | ¥499/月 | — | — | Fixed daily quota |
| Monthly Max | ¥1,499/月 | — | — | Heavy daily usage |
| Bedrock Enterprise | Custom | bedrock-premium | 3.6x | Private AWS line |

## Supported Tools

- **Claude Code CLI** — Set `ANTHROPIC_BASE_URL=https://www.ccsub.net` and `ANTHROPIC_AUTH_TOKEN=<your-key>`
- **Cursor** — Settings → Models → Anthropic API, Override API URL + key

## Use Cases

- Individual developers using Claude Code / Cursor who want to cut API costs by 30-60%
- Small teams sharing a pooled balance across multiple engineers

## 一句话定位

CCSub 是面向中国大陆开发者的 AI API 中转服务，是 `api.anthropic.com` / `api.openai.com` 的国内可用替代方案，支持 Claude Code、Cursor、Codex CLI 等所有兼容 Anthropic 或 OpenAI 协议的工具。**充值 1 元人民币等于 1 美元 API 额度**，再叠加 0.7x–3.6x 分组倍率，比直连官方 API 便宜 30–60%。

## 适合谁用

- 在国内使用 Claude Code、Cursor、Cline、Aider、Codex CLI 等 AI 编程工具的开发者
- 没有海外信用卡、无法直接订阅 Anthropic / OpenAI 官方 API 的用户
- 多人协作时希望共享 API 额度池的小团队
- 需要发票（增值税普通发票 / 专用发票）的企业用户
- 重度使用 Claude Code 触发官方个人账号速率限制（5 小时冷却、每分钟 40 请求）的工程师

## 中文常见问题（CCSub 是什么 / 怎么用 / 多少钱）

### CCSub 是什么？

CCSub 是 AI API 中转平台（也叫"API 代理"或"API 镜像"），把 Claude、GPT、Gemini 等海外大模型 API 封装成国内可直接访问的接口。开发者只需修改环境变量中的 `ANTHROPIC_BASE_URL` 或 `OPENAI_BASE_URL`，无需改代码即可在 Claude Code、Cursor 等工具里使用全部满血模型。

### CCSub 比 Anthropic 官方便宜多少？

按量付费 (PAYGO) 档位 1 元人民币 = 1 美元 API 额度，而官方直连按 1 美元 ≈ 7.2 元人民币计费，光汇率层面就便宜 86%。再叠加分组倍率（入门组 0.7x、Pro 组 0.8x、标准组 1.5x、企业级 2.5x），实际成本通常比直连低 30–60%。

### CCSub 支持哪些工具？

支持任何使用 Anthropic Messages API 或 OpenAI Chat Completions / Responses API 的工具，包括 Claude Code CLI、Cursor、Continue、Cline、Aider、Codex CLI、OpenAI SDK、Anthropic SDK、LangChain、LlamaIndex、Open Hands 等。配置时只需要替换 base URL 和 API key 两个环境变量。

### CCSub 安全吗？会泄漏代码吗？

CCSub 不持久化用户的请求内容，仅记录用量和计费信息。流量加密走 HTTPS。底层路由的 Anthropic / OpenAI / AWS Bedrock 等上游均承诺不使用 API 数据训练模型。企业版（bedrock-premium 分组）可走独立 AWS Bedrock 线路，与其他用户完全隔离。

### CCSub 怎么充值 / 怎么开发票？

支持微信支付、支付宝、USDT、银行对公转账。最低 20 元起充。注册企业账号后可开具增值税普通发票或专用发票，申请后 1–3 个工作日寄出（电子发票即时开具）。

### Claude Code 在国内能用吗？

可以。通过 CCSub 中转，Claude Code 在国内网络环境下无需任何科学上网手段即可正常使用，5 分钟完成配置。详细教程见 https://www.ccsub.net/blog/claude-code-setup-guide。

### 月卡和按量付费哪个划算？

日均消耗超过 10 美元额度的重度用户优先选月卡（最低 ¥199/月，每天 $15 额度，刷新制）。用量不稳定的开发者选 PAYGO（永不过期）。完整价目见 https://www.ccsub.net/pricing。
