# BankBridge with Vertex AI

Updated Apr 23, 2026·2 min read

Direct answer: 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.
