google adk - how to consume agent deployed to vertex ai or agentic platform

Consuming using Vertex AI Python Library

To consume Agentic Platform (Vertex AI), we just need to use the following code to call from python.

So the endpoint can be obtained from here:

Then ensure you have the vertexai libraries installed. You can use either this PYPI package - google-cloud-aiplatform or google-adk. 

And then we have the codes here 

import asyncio

import vertexai

LOCATION = "us-central1"

client = vertexai.Client(

    location=LOCATION,

)

# Copy from your AI Platform

REASONING_ENGINE_ID = "projects/PROJECT_ID/locations/us-central1/reasoningEngines/ENGINE_ID"

# if REASONING_ENGINE_ID is None:

#     try:

#         with open("../deployment_metadata.json") as f:

#             metadata = json.load(f)

#             REASONING_ENGINE_ID = metadata.get("remote_agent_engine_id")

#     except (FileNotFoundError, json.JSONDecodeError):

#         pass

async def main():

    print(f"Using REASONING_ENGINE_ID: {REASONING_ENGINE_ID}")

    # Get the existing agent engine

    remote_agent_engine = client.agent_engines.get(name=REASONING_ENGINE_ID)

    async for event in remote_agent_engine.async_stream_query(

        message="hi!", user_id="test"

    ):

        print(event)

asyncio.run(main())

After you run this command, you can see it is being invoke in Agentic platform
