Router One

Gemini API in China — no VPN, no foreign card

Router One makes Gemini models callable from Mainland China without a VPN or foreign card: the same OpenAI-compatible endpoint https://api.router.one/v1 and key that reach GPT, Claude and DeepSeek, billed per token with a cost trace for every request. Google's own Gemini endpoints are blocked for mainland networks and bill to a foreign card; the gateway removes both blockers.

Direct access, no VPN

Gemini models answer through the OpenAI-compatible endpoint at https://api.router.one/v1. Review the published benchmark below before relying on any point-in-time network result.

Million-token context

Gemini's long-context models (up to 1M tokens on select models) are in the catalog with live pricing — long documents, codebases, and multimodal inputs included.

Pay in RMB

Top up with a card or Alipay through one hosted checkout, or with USDT/USDC on six chains. Metered per token, pay-as-you-go — no Google Cloud billing account needed.

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.

Gemini models in the catalog

Model IDs as you pass them in the model field — the lineup follows the live catalog, and current per-token rates, context windows, and capability tags are on the models page.

google/gemini-3.6-flashPrevious Flash generation — 1M context, 64K max output, vision and tool calling
google/gemini-3.5-flashEarlier Flash generation — same 1M context and 64K max output; keep it for prompts already validated on it

3-step setup

Any OpenAI-compatible client works — set the base URL, pick a Gemini model ID from the catalog, and call.

  1. 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.
  2. 2Point your client at the gatewaySet the base URL to https://api.router.one/v1 in the OpenAI SDK or any compatible tool, and use a Gemini model ID copied from the /models page.
  3. 3Send a request and verifyMake a chat completion call, then open Dashboard → Logs to see the trace: model, tokens, latency, and cost for the request.
gemini-via-router-one.sh
# Gemini via the OpenAI-compatible endpoint
curl -X POST https://api.router.one/v1/chat/completions \
  -H "Authorization: Bearer sk-your-router-one-key" \
  -H "Content-Type: application/json" \
  -d '{"model": "<gemini-model-id>",
       "messages": [{"role": "user", "content": "你好"}]}'

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.

FAQ

Why can't I call the Gemini API directly from China?

Google blocks its Generative AI endpoints for Mainland China network space, and billing requires a foreign card. A VPN adds latency and instability; a China-reachable gateway avoids both.

Which Gemini models are available?

The chat lineup currently spans google/gemini-3.7-flash, google/gemini-3.6-flash, google/gemini-3.5-flash and google/gemini-3-flash-preview on the Flash side, and google/gemini-3.1-pro-preview and google/gemini-3-pro-preview-11-2025 on the Pro side. The catalog updates as models ship or retire, so treat /models as the source of truth for the live lineup, per-token rates, context windows, and capability tags.

Do I use Google's SDK?

No — you call Gemini models through the OpenAI-compatible interface: the official OpenAI SDK, curl, or any compatible client. Vision input works via standard image_url content parts.

How does pricing compare to official rates?

Billing is metered per token with discounted rates on select models — the /models page shows every Gemini model's current effective price, struck through against its base rate.

Is there a detailed setup guide?

Yes — the Gemini API China guide on the blog walks through configuration step by step, including model selection and common errors.
