Claude Code in China — Anthropic-compatible, no VPN

Router One runs Claude Code from Mainland China without a VPN: point ANTHROPIC_BASE_URL at the Anthropic-compatible endpoint https://api.router.one, use a Router One key, and pay per token from a wallet topped up by card or Alipay (or USDT/USDC on six chains) — no foreign credit card, and a cost trace on every request. Reaching Anthropic's own API from the mainland is slow and unreliable and bills to a foreign card; the gateway removes both blockers.

Direct access, no VPN

Claude Code uses the Anthropic-compatible endpoint at https://api.router.one. Review the published benchmark below before relying on any point-in-time network result.

Pay in RMB

Top up with a card or Alipay through one hosted checkout, or with USDT/USDC on six chains. No foreign credit card required.

Paid-usage headroom

No low fixed cap for normal paid usage. Abuse prevention, per-account protection limits, and upstream constraints may still apply; if a request returns 429, check Dashboard -> Logs or contact support to raise limits.

Review the China latency benchmark

This setup guide does not make a separate latency promise. The published snapshot, last updated 2026-05-15, covers Beijing, Shanghai, and Shenzhen on China Telecom, China Unicom, and China Mobile in a rolling 7-day window. It is not an SLA, and individual networks may vary; review the full method and caveats before judging fit for your workload.

2-minute setup

If you have Claude Code installed, export two variables and relaunch. Persistent setup: add these lines to ~/.zshrc or ~/.bashrc. ANTHROPIC_API_KEY is not required — leave it unset.

1Create a Router One API keySign up at router.one and create an API key in the dashboard. Top up with a card or Alipay on the hosted checkout, or with USDT/USDC — no foreign credit card required.
2Point Claude Code at Router OneExport ANTHROPIC_BASE_URL=https://api.router.one and ANTHROPIC_AUTH_TOKEN set to your Router One key. ANTHROPIC_API_KEY is not required; unset it if you exported it earlier. Add the lines to ~/.zshrc or ~/.bashrc to persist them.
3Relaunch Claude CodeRestart Claude Code. Requests now route through Router One's China-reachable, Anthropic-compatible endpoint with no VPN.

terminal

# Point Claude Code at Router One
export ANTHROPIC_BASE_URL=https://api.router.one
export ANTHROPIC_AUTH_TOKEN=sk-your-router-one-key

FAQ

Do I need a VPN?

No proxy or VPN is required for the Router One endpoint. The benchmark below documents the dated network snapshot and its caveats.

How does billing work?

Use prepaid wallet balance or a live subscription plan. Top up with a card or Alipay in one hosted checkout, or with USDT/USDC on six chains — usage outside plan coverage is still metered per token.

Is my data stored?

No. Router One proxies requests in real time; prompts and completions are not persisted. We log only metadata (model, tokens, latency, cost) for billing and observability.

What if the upstream Anthropic API goes down?

Claude Code traffic routes through Router One's infrastructure with automatic failover. When upstream issues occur, requests are retried or redirected transparently.

Can I run DeepSeek V4 inside Claude Code?

Yes. Keep the same ANTHROPIC_BASE_URL and set the model ID to deepseek-v4-pro or deepseek-v4-flash (the /model command switches mid-session). Router One serves DeepSeek V4 over the same Anthropic-compatible endpoint as the Claude family, so the request lands in the same traces and wallet. Context window and live rates: /models/deepseek-v4-pro.
