Get specific rates while coding in Cursor.

When you need a rate, call `get_exchange_rate_for_currency` and the live result gets injected right where your cursor is. This means you write code that uses real API responses—no stubs required. It’s perfect for writing functions that rely on current official rates, like calculating conversion amounts in a financial script.

Query complex data structures using Cursor.

Write your code to use `query_treasury_dataset` and specify the endpoint path. The agent mode handles calling the API, so you get live data into your function body. You'll be pulling structured results—filtering, sorting, everything—without ever leaving the editor or switching contexts.

Handle 170+ currencies in Cursor.

Need to process multiple currency values? Use `get_treasury_exchange_rates` within your code block. The function returns a comprehensive set of official rates for over 170 global currencies. Your code can then loop through this data, making it ideal for bulk processing tasks in production.
