curl https://api.openai.com/v1/models \
  -H "Authorization: Bearer $OPENAI_API_KEY" \
  -H "OpenAI-Organization: org-lEOCXdqO48RKaa66ZdhPseo7" \

    ^^^^^^^^^^^^^^^^^^

If we are working on several projects, you can specify which of the given requests belong to:

$open_ai_key = getenv('OPENAI_API_KEY');
$open_ai = new OpenAi($open_ai_key);
$open_ai->setProject('<YOUR-PROJECT-ID>'); // `proj_XXX`
