Quick note: we now have a shared Claude Code (CC) pool with roughly $100/day of trial credit. You can use it to validate your real workflows first, then decide whether a monthly pass or Codex carpool fits your budget.
Why this page is worth bookmarking
- Aligned with the official page: This portal is based on the Chinese Claude Code & Codex plan page at tool.rexai.top, so pricing, limits and usage guidelines stay in sync.
- Clear division of roles: Claude Code excels at understanding and refactoring entire projects; Codex shines at quick completions, scripts and SQL. Used together, they balance cost, latency and quality.
- Built for conversion: At the bottom you’ll find a QR code and direct Xianyu link, so readers can move from “just curious” to “try → buy → track usage” in one flow.
Claude Code × Codex at a glance
| Model | Strength | Typical scenarios |
|---|---|---|
| Claude Code | Reading and refactoring whole codebases, understanding cross-file dependencies, explaining legacy business logic, and applying edits directly inside your IDE | Large refactors, onboarding to unfamiliar projects, documenting systems, reviewing and cleaning up complex PRs |
| Codex | Fast writing and completion for short prompts and high‑frequency calls | Implementing functions, scripts and SQL, generating tests, and rapidly rewriting or refactoring snippets |
Suggested combo: let Claude Code think through the architecture and big changes, and let Codex handle rapid-fire completions. Use the usage dashboard to observe your 7‑day / 30‑day spend curve.
RMB pricing & carpool options
Claude Code monthly passes (for heavier usage)
| Plan | Monthly price | Approx. daily USD credit | Best for |
|---|---|---|---|
| CC Pass · ~$35/day | ¥400 / month | ~USD 35 per day | Full‑time developers who live in refactors and large codebases |
| CC Pass · ~$25/day | ¥300 / month | ~USD 25 per day | Day job + side projects, or regular evening coding sessions |
| CC Pass · ~$15/day | ¥180 / month | ~USD 15 per day | Moderate users focused on debugging, small tools and scripts |
Note: actual available credit can fluctuate slightly based on real billing. The usage dashboard gives a more intuitive view over the last 7 / 30 days.
Codex carpool (split cost by seat)
| Car type | Monthly price | Experience |
|---|---|---|
| 4‑seat car | ¥300 / month | Best per‑person price, ideal for light to moderate coding usage |
| 3‑seat car | ¥400 / month | More stable bandwidth and concurrency, suited to frequent completions and automation workloads |
Think of Codex as your high‑frequency typist: the more short prompts and repeated calls you make, the more value you squeeze out of each seat.
Three steps to plug it into your workflow
- Read the integration docs:
https://happycoding.onlinecovers auth, model catalog and basic API examples. Start by mirroring the official requests. - Install the config switcher: the open-source
claude-config-switcherhelps you quickly swap between CC and Codex keys in your local environment via CLI. - Dive into the Code docs: a Feishu (Lark) Wiki hosts more examples and best practices. If you can’t access it directly, ask in the user group for the latest link.
How to buy and get support
- Detailed purchasing, scheduling and support policies are consolidated in the Xianyu listing “codex 月卡无周限额”.
- You can either copy the link or scan the QR code to open it in Taobao/Xianyu:

FAQ
- Can I try it before paying? Yes. The shared CC pool exposes around USD 100/day of trial credit so you can run your real scenarios first.
- What does the stats page show? It summarizes your last 7 / 30 days of spending, call counts per model and error breakdowns, so you can keep close tabs on cost.
- Can one person use both CC and Codex? Absolutely. The recommended pattern is “CC thinks, Codex types”—CC for global reasoning and large changes, Codex for high‑frequency completions—so you get strong results without overspending.
