Additional information

The composition of Azure OpenAI API URL's may be in appropriately assembled by the codex package as this pattern worked for me; while codex refused.

curl https://`<project.name>`.openai.azure.com/openai/deployments/`<deployment-id>`/chat/completions?api-version=`<api.version>` \
  -H "Content-Type: application/json" \
  -H "api-key: `<key.value>`" \
  -d '{
    "messages": [{"role": "user", "content": "Say Hello"}],
    "temperature": 0,
    "max_tokens": 50
  }'
