vertexai.init(
    project=PROJECT_ID,
    location=LOCATION,
    api_endpoint="gateway.helicone.ai",
    api_transport="rest",  # Must be 'rest' or else it will not work
    request_metadata=[
        ('helicone-target-url', f'https://{LOCATION}-aiplatform.googleapis.com'),
        ('helicone-auth', f'Bearer {HELICONE_API_KEY}')
