Google ADK (gateway)

Route Google ADK model calls through the Respan gateway to use models and provider credentials configured in Respan. The gateway setup uses RESPAN_API_KEY for the model request path.

Paste this into your coding agent:

Setup

Install packages

Terminal


pip install "google-adk[extensions]"

Set environment variables

export RESPAN_API_KEY="YOUR_RESPAN_API_KEY"

No provider credentials are needed in your application when the request is routed through the Respan gateway.

Point ADK to the Respan gateway

Python


import os
from google.adk.agents import Agent
from google.adk.models.lite_llm import LiteLlm

agent = Agent(
    name="assistant",
    model=LiteLlm(
        model="gpt-5-mini",
        api_key=os.environ["RESPAN_API_KEY"],
        api_base="https://gateway.respan.ai",
    ),
    instruction="You are a concise assistant.",
)
