Perplexity

Populate Code with Congressional Member Data

The `list_congress_members` tool pulls current and past members of the US Congress. In Agent mode, you can write a function that accepts a member's name and injects their actual service record directly into your code block. Need to filter by committee? The server also provides `list_congress_committees`, letting your AI generate validated lists based on congressional structure.

Build Legislative Tracking Code

To track bills, use the `get_bill_details` tool. When you write code that needs to display bill information, the AI calls this function and uses the live response—not fake data—to populate your variables. You can pair this with `list_congress_bills` to first fetch a list of relevant bills, then loop through them using their details.

Code-Gen for Congressional History

Generating historical reports is easy. The `list_congress_sessions` tool pulls session start and end dates. You can write code that iterates over multiple Congress numbers, ensuring your script covers decades of legislative history. For treaties, the `list_congress_treaties` function provides structured data you can immediately use in your application's database calls.
