Wire Chinese models into the tools you already code in
Five tested guides covering Codex CLI, Claude Code, and IDE agents, plus an error reference that tells you which layer actually broke. Every claim was verified against real requests, with the date we checked it.
Codex CLI with DeepSeek: Responses configuration and 404 troubleshooting
Current Codex supports the Responses protocol only. Configure the provider and API key, probe the endpoint, and learn what to do when a gateway only offers Chat Completions.
Claude Code with a third-party model: what stops working
Claude Code still works after you swap the model — but not every feature survives. This breaks the tool down into client layer, protocol layer and model layer, then says item by item what breaks, what does not, and whether the loss can be recovered.
Using Claude Code without an overseas credit card (2026)
An official Claude subscription needs a foreign card, which stops a lot of people at the door. This compares four workable routes on cost, friction and risk, then walks through the CNY pay-as-you-go one with cost estimates by usage level.
Cursor, Cline and Roo Code with DeepSeek: a config matrix
The three IDE agents are configured differently and fail differently. This gives one comparison matrix, per-tool setup steps, and a close look at the two problems nobody avoids: a hardcoded context window and incompatible tool-call formats.
Claude Code and Codex error reference for third-party APIs
The same error line often has completely different causes when you go direct versus through a gateway. This reference is organised in five layers — network, auth, protocol, model, context — with a copy-paste probe and a decision rule for each.
One key, four protocols
A single API key works with the OpenAI, Anthropic, Responses, and Gemini protocols. Billed in CNY, top up from ¥10.
