OpenAI-compatible API	Yes — Chat Completions, drop-in base URL	Yes — OpenAI-compatible gateway
Account requirement	Standalone account — no US card or platform lock-in	Routed through a Vercel account
Accessible from Mainland China	China-reachable endpoint with published latency benchmark	Global edge routing; not China-specific
Payment methods	Card or Alipay in one checkout, USDT/USDC on 6 chains	Card and credits through a Vercel account

Where Router One helps

First-class AI coding tools

Claude Code and OpenAI Codex CLI work natively with Router One — Claude Code via ANTHROPIC_BASE_URL plus ANTHROPIC_AUTH_TOKEN, Codex CLI via a ~/.codex/config.toml provider with wire_api = "responses" — with automatic failover during upstream outages. One-click install scripts set both up.

Pay your way

Pay by card or in RMB with Alipay through one hosted checkout, or with USDT and USDC on six chains (Tron, BSC, Ethereum, Polygon, Base, Arbitrum) — from one wallet flow, on a standalone account.

One endpoint, reachable worldwide

Distributed teams keep one integration everywhere — global edge gateways can be inconsistent from some Mainland China networks, while Router One stays reachable there too. 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.

Switch with one base URL change

Router One speaks the OpenAI Chat Completions API, so most Vercel AI Gateway integrations move with a base URL and key change — including SDKs and CLI tools that read OPENAI_BASE_URL.

terminal

# Point your client at Router One
export OPENAI_BASE_URL=https://api.router.one/v1
export OPENAI_API_KEY=sk-your-router-one-key

FAQ

Is Router One OpenAI-compatible like Vercel AI Gateway?

Yes. Router One speaks the OpenAI Chat Completions API, so any library or tool that targets an OpenAI-compatible gateway works by changing the base URL.

Can I migrate from Vercel AI Gateway?

Yes. Update the base URL and API key and you are done. SDKs and tools that read OPENAI_BASE_URL pick up Router One immediately; Claude Code and Codex CLI each have a one-click install script.

Do I need a Vercel account?

No. Router One is a standalone account with its own wallet and billing, so there is no platform lock-in and no US credit card requirement.

How does pricing work?

Router One supports pay-per-token wallet billing and live subscription plans. See each model's rate on the models page and current plan options on the pricing page.
