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
```
3
Send the first request
Use any model id from the catalog. Cost is estimated and held before the call, then settled against actual usage.
Model
curl
```
curl https://routerbase.seeksvc.com/v1/chat/completions \
  -H "Authorization: Bearer $ROUTERBASE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "anthropic/claude-haiku-4.5",
    "messages": [{"role": "user", "content": "Hello"}]
  }'
```
Python
```
from openai import OpenAI

client = OpenAI(
    base_url="https://routerbase.seeksvc.com/v1",
    api_key="sk-rb-...",  # create one at /dashboard/keys
)

resp = client.chat.completions.create(
    model="anthropic/claude-haiku-4.5",
    messages=[{"role": "user", "content": "Hello"}],
)
print(resp.choices[0].message.content)
```
Node
```
import OpenAI from "openai"

const client = new OpenAI({
  baseURL: "https://routerbase.seeksvc.com/v1",
  apiKey: process.env.ROUTERBASE_API_KEY,
})

const resp = await client.chat.completions.create({
  model: "anthropic/claude-haiku-4.5",
  messages: [{ role: "user", content: "Hello" }],
})
console.log(resp.choices[0].message.content)
```
