Hi Russell,

**************************************************
Make your first API call across every major model.
**************************************************

The request below is small, but what it proves is not: a live response, routed to the best provider for the model you pick, failover standing by, token counts in the reply. Every model you will ever switch to works through this same call. Swap the slug for anything on the rankings ( openrouter.ai/rankings?utm_campaign=on…customerio ) and the same code keeps working.

Paste and run

from openrouter import OpenRouter import os with OpenRouter(api_key=os.getenv("OPENROUTER_API_KEY")) as client:
response = client.chat.send
( model="~openai/gpt-latest",
messages=[
{"role": "user", "content": "What is the meaning of life?"}
], )

print(response.choices[0].message.content)

Open the quickstart ( openrouter.ai/docs/quickstart?utm_camp…customerio )

The life of that request

1. It lands at the router

OpenRouter resolves your model slug against every live provider serving it, weighing uptime, latency, and price.

2. It runs with standbys

If the chosen provider degrades mid-request, the next-best one picks up. Your code never sees the swap.

3. It returns with receipts

The response carries token counts, so cost tracking and observability start from request one.

Rather generate the request in your own language? The interactive Request Builder ( openrouter.ai/request-builder?utm_camp…customerio ) writes it for you.

No credits on the account yet? Models tagged :free ( openrouter.ai/models?max_price=0&utm_c…customerio ) run the same call on the free tier, no card needed.

Stuck on anything? Reply. A person reads every one.
