Mortgage Rate Capture
This guide shows how to use Browserbase with IBM watsonx.ai to create a mortgage rate analysis tool. The integration captures screenshots of mortgage rate data from Freddie Mac’s website and uses a vision model to analyze and summarize the rates
Here are the steps:
- Set up your environment
- Capture a web page screenshot
- Analyze the screenshot with IBM watsonx.ai
- Create a mortgage rate report
Build a Mortgage Rate Analysis Tool
1. Set up your environment
Install the required dependencies and set up your API keys.
Create a .env
file with your API keys:
- IBM watsonx.ai API key and Project ID
- Browserbase Project ID & API Key
Make sure to install Playwright dependencies after installation by running playwright install
in your terminal.
2. Capture a web page screenshot
Use Browserbase to navigate to the Freddie Mac mortgage rates page and capture a screenshot of the rate information that’s embedded in an iframe:
3. Analyze the screenshot with IBM watsonx.ai
Now, use IBM watsonx.ai’s vision model to analyze the captured screenshot and extract the mortgage rate information:
4. Create a mortgage rate report
Combine the screenshot capture and analysis steps into a complete solution that produces a nicely formatted report.
Example output:
🎉 You’ve created a mortgage rate analysis tool with IBM watsonx.ai and Browserbase!
Next Steps
With this foundation, you can build more advanced workflows:
- Schedule regular rate checks and track trends over time
- Compare rates across multiple mortgage providers
- Create dashboards to monitor rate changes and predict future trends
- Fill out mortgage applications using extracted data
Best Practices
- Handle dynamic content: Some websites load data asynchronously; ensure content is fully loaded by adding wait times before capturing screenshots.
- Add error handling: Implement robust error handling for network issues and page structure changes.
- Secure your credentials: Never expose API keys in client-side code or public repositories.
