Quickstart
Two lines: point the OpenAI client at us, pass model="auto". That's it.
1. Grab a key
Sign up — no credit card. You get 100K tokens/month BYOK plus a $5 managed-key trial.
Get Your API Key →2. Make your first call
pip install openai # the official OpenAI SDK
from openai import OpenAI
client = OpenAI(
api_key="kr-your-key",
base_url="https://api.kairosroute.com/v1",
)
resp = client.chat.completions.create(
model="auto", # let the router pick
messages=[{"role": "user", "content": "Explain quantum computing simply."}],
)
print(resp.choices[0].message.content)Replace kr-your-key with the key from your dashboard. Any OpenAI-compatible client works — change two lines, done.
3. Check the receipt
Every request leaves a receipt in the dashboard — model picked, input/output tokens, cost, latency, fallback hops if any. Your first call shows up within a second.
