GET STARTED

Your first call, in three steps

If you already use an OpenAI-compatible client, the only thing that changes is the base URL.

1
Create an API key
Keys start with sk-rb-. The plaintext is shown once, at creation — we store only a hash, so nobody (including us) can read it back. Copy it then.
Create an account
2
Point your client at this base URL
Any OpenAI SDK works as-is. Set the base URL and pass your key as the bearer token.
Base URL
```
https://routerbase.seeksvc.com/v1
```

Send the first request

Use any model id from the catalog. Cost is estimated and held before the call, then settled against actual usage.
