# BankBridge with Vertex AI

Updated Apr 23, 2026·2 min read

Add BankBridge to Vertex AI once, then ask it about your real bank accounts, transactions, subscriptions, and investment holdings. Every question live-fetches in real time — nothing is cached. $5/mo per connected bank.

## Setup

Paste the config below into `google-genai SDK`. Swap the placeholder key for your real `bbk_` key from [your dashboard](/dashboard/settings).

```
from google import genai
from google.genai import types

client = genai.Client(vertexai=True, project="your-project", location="us-central1")

response = client.models.generate_content(
    model="gemini-2.0-flash",
    contents="How much did I spend on restaurants last month?",
    config=types.GenerateContentConfig(
        tools=[
            types.Tool(
                mcp=types.McpTool(
                    endpoint="https://bankbridge.money/api/mcp",
                    headers={"Authorization": "Bearer bbk_your_api_key_here"},
                )
            )
        ]
    ),
)
print(response.text)
```

The [full doc page](/docs/vertex-ai) for Vertex AIauto-fills your real key when you’re signed in.

## Three prompts to try

-   > “List my bank accounts and current balances.”
    
-   > “How much did I spend on food this month?”
    
-   > “What are my recurring subscriptions?”
    

## If it doesn’t work

Check the [Vertex AI doc page](/docs/vertex-ai) for the Troubleshooting section. 90% of first-time failures are either a missing `Bearer` prefix (note the space) or a placeholder key that didn’t get replaced with a real one.
