Router One

Router One is a unified LLM API gateway for teams that build on frontier models. Instead of opening separate accounts, keys and SDKs for OpenAI, Anthropic, Google and xAI, you point your existing client at one base URL, https://api.router.one/v1, and keep shipping. The gateway is both OpenAI- and Anthropic-compatible: Chat Completions, the Responses API and the Messages API all work, so applications, Claude Code and Codex CLI can be redirected with a couple of environment variables or a few lines of configuration. Routing is the core product. A request names one exact model, and the gateway selects a healthy provider route for it; if that route returns a retryable error, Router One can try another eligible route serving the same requested model and record the final result, without implying cross-model substitution. Everything is observed: each request gets an ID, and Customer Logs show the model, tokens, settled cost, recorded latency and status, with upstream supplier identities kept internal. You control spend per key with a maxSpend cap and optional expiry, while rate and token limits follow platform defaults that can be raised on request. Billing is flexible. Top up a prepaid USD wallet by card, Alipay, or USDT/USDC on six chains, then pay each model's posted per-token rate, with select models as low as 10% of official list prices. Alternatively, Pro, Max and Ultra subscriptions grant shared monthly request quotas per model tier, and calls outside coverage draw on the wallet. The catalog holds 30+ models from GPT, Claude, Gemini and Grok families, the platform is reachable from mainland China without a VPN, and no prompt or response bodies from direct API calls are retained. Router One also ships a playground, integration guides for Cursor and desktop clients, image-generation endpoints, a cost calculator, a public China latency benchmark, a status page and a documented pricing methodology, so teams can verify claims before moving production traffic. The gateway is not an agent runtime: workflows, state and tool execution stay in your application. Subscriptions and wallet billing can run together, invoices are issued automatically for card and Alipay payments, wallet top-ups never expire, and unused subscription requests do not roll over between cycles.
