Router One

GPT API access, up to 90% off list price

If your product runs on GPT-family models, the token bill is the product's biggest line item. Router One resells metered access through one gateway: select GPT models go as low as 10% of official list prices, the endpoint speaks both Chat Completions and the newer Responses API wire format, and you can top up without a US credit card — with a cost trace on every request.

Up to 90% off, verifiable

Select GPT models run as low as 10% of official list prices. The /models page is the live price sheet — every rate shown struck through against its base rate.

Chat Completions + Responses API

The gateway implements /v1/chat/completions for every model and the native /v1/responses wire format — which is what makes Codex CLI work where most relays 404.

Pay without a US card

Top up with Alipay, WeChat Pay, Stripe, or USDT/USDC on six networks. Wallet balance never expires; subscription plans are live for heavy usage.

How the discount works

  1. 1Metered per token, prepaid walletYou pay the discounted per-token rate shown on the model page — no seats, no minimum commitment. Wallet balance is drawn down per request.
  2. 2The catalog is the price sheetEvery GPT model lists its current input/output and cache rates on /models, struck through against the base rate, so you can verify the discount before calling.
  3. 3Documented methodologyHow Router One sources capacity and sets prices is written up on the pricing methodology page — no mystery meat.

First GPT call in 3 steps

Create a key, top up in your currency, and point any OpenAI-compatible client at the gateway — reachable from Mainland China without a VPN.

  1. 1Create an API keySign up at router.one and create a key in the dashboard. Top up with Alipay, WeChat Pay, Stripe, or USDT/USDC — no US credit card required.
  2. 2Point your client at the gatewaySet the base URL to https://api.router.one/v1 in any OpenAI SDK or tool. Codex CLI users keep wire_api = "responses" — the gateway implements it natively.
  3. 3Verify the cost traceOpen Dashboard → Logs after your first request to see model, tokens, latency, and the exact discounted cost per call.
gpt-via-router-one.sh
# OpenAI-compatible — only the base URL changes
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": "<gpt-model-id>",
       "messages": [{"role": "user", "content": "Hello!"}]}'

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 is it cheaper than list price?

Router One aggregates demand across many customers and routes over pooled, committed capacity, then passes the margin down as discounted per-token rates. The approach is documented on the pricing methodology page; the /models page always shows the current effective rate.

Is this the official OpenAI API?

Router One is an independent gateway, not OpenAI — requests are routed to language models operated by third-party providers, and the wire formats are identical (Chat Completions and the Responses API). Model names and trademarks belong to their owners.

Does Codex CLI work with it?

Yes — natively. Codex speaks the Responses API wire format, which Router One implements at /v1/responses. Point base_url at the gateway and keep wire_api = "responses"; the Codex China guide has the full config.toml.

Which GPT models are available?

The current GPT-5.x lineup, codex variants, and o-series reasoning models are listed on /models with live per-token pricing, context windows, and capabilities. Discount levels vary by model.

Will my existing OpenAI SDK code work?

Yes — change the base URL and key in the client constructor and keep everything else: chat completions, streaming, and tool calls all use the standard interface.

Can I use it from Mainland China?

Yes. Based on the China latency benchmark last updated 2026-05-15, Router One measured 110-130ms p50 across Beijing, Shanghai, and Shenzhen; individual networks may vary.
