/ monorouter

Any Claude Pro or Max.
Any OpenAI key.
One API endpoint.

No more topping up Anthropic API credits while also paying for Claude. Anonymous signup, live analytics, 1,500 free calls, $5 in crypto for 30 more days.

// what you get
[ multi-provider ]
one endpoint, routes anthropic + openai calls to the right provider based on the model name.
[ anonymous ]
handle + password only. no email, no personal data. 6 one-time recovery codes at signup.
[ encrypted ]
aes-256-gcm token storage at rest. argon2id password hashing. jwt sessions with version invalidation.
[ analytics ]
live dashboard: requests, tokens, cost, latency. breakdowns per model, api key, provider, provider token.
[ auto-connect ]
one-liner `curl | bash` (or powershell) extracts your claude max oauth token locally. no manual paste.
// common questions
[ Is there a launch offer right now? ]
Yes. New signups through April 30, 2026 (UTC) get 15 days of unlimited routed calls on top of the standard 1,500-call free tier. The grant is applied automatically the moment you sign up — no code, no card. Calls you make during the 15-day window do not count against the post-promo free quota.
[ Does this work with Claude Pro or only Claude Max? ]
Both. MonoRouter uses the same Anthropic OAuth flow Claude Code exposes — whichever tier your Anthropic account has (Pro or Max), routed requests bill against that subscription. No separate Anthropic API credits needed.
[ Which clients does MonoRouter support? ]
Any client that speaks the Anthropic Messages API (Claude Code, OpenClaw, Cursor, Cline, the official Anthropic SDKs) or the OpenAI Chat Completions API. Point the client at api.monorouter.dev and use your mrk_* key as the apiKey.
[ How is my Claude OAuth token stored? ]
AES-256-GCM encrypted at rest using a key that lives only on the server. We decrypt it in-memory to route a request and never display it back to you. Argon2id for password hashes, JWT sessions with version invalidation.
[ What are the free-tier limits? ]
1,500 successful API calls per account, lifetime. Failed calls do not count against the quota. After that, $5 in crypto gets you 30 days of unlimited calls — one-time, nothing auto-renews.
[ Is it really anonymous? ]
Yes. Signup is a handle plus password, no email, no personal details. We do not log IP addresses persistently. Your handle is the entire identity.
[ What happens if the service goes down or I want to leave? ]
Delete your account at /settings — the user row, tokens, usage events, and subscription all go with it. If we ever shut the service down we will post notice on the landing page; your Anthropic account and subscription are unaffected either way.
// what this is NOT
nota credential-sharing service — you bring your own anthropic oauth / openai key.
nota replacement for provider billing — anthropic + openai still bill you for actual usage.
notan enterprise sso gateway — single-user, self-serve, anonymous.
nota code editor or agent — just a routing proxy with a dashboard.
notaffiliated with anthropic or openai.
