The Current Interest Rates API Features

The Current Interest Rates API provides a straightforward way to access interest rate information from various central banks. Users can simply run the API to obtain the latest interest rates, which is particularly useful for financial analysis and market research.

For instance, when querying the current interest rates, the API returns a response that includes details about different central banks:

{"central_bank_rates": [{"central_bank": "Australian Central Bank", "country": "Australia", "rate_pct": 4.35, "last_updated": "11-08-2023"}, {"central_bank": "British Central Bank", "country": "United Kingdom", "rate_pct": 4.75, "last_updated": "11-07-2024"}]}

In this response, the fields represent:
