The whole idea, in one request

EU-Router supports the documented OpenAI-compatible chat subset. If you have ever called /v1/chat/completions, you already know how to use it:

hello-europe.sh

curl $EU_ROUTER_BASE_URL/v1/chat/completions \
  -H "Authorization: Bearer $EU_ROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model": "<model-from-v1-models>", "messages": [{"role": "user", "content": "Hello, Europe."}]}'
