Side-by-Side Feature Comparison

Key Features of USA Interest Rate API

One of the standout features of the USA Interest Rate API is its capability to calculate sales taxes based on specific locations. To utilize this feature, users must provide a zip code, with optional parameters for city and state to refine their queries. This ensures that businesses can accurately determine the applicable sales tax rates for their transactions.

For example, when querying the sales tax for a specific zip code, the API returns a JSON response that includes:

[{"zip_code": "75001", "total_rate": "0.082500", "state_rate": "0.062500", "city_rate": "0.010000", "county_rate": "0.000000", "additional_rate": "0.010000"}]

In this response, the fields represent:

• zip_code: The zip code for which the sales tax is calculated.
• total_rate: The total sales tax rate applicable.
• state_rate: The state-specific sales tax rate.
• city_rate: The city-specific sales tax rate.
• county_rate: The county-specific sales tax rate.
• additional_rate: Any additional sales tax that may apply.

This feature is particularly useful for e-commerce platforms that need to automate sales tax calculations based on the customer's location, ensuring compliance with local tax laws.

Key Features of Global Interest Rates API

The Global Interest Rates API offers a feature that allows users to access interest rates set by central banks and various benchmark rates. To use this feature, users must specify the name of a country to retrieve its central bank rates or the name of a non-central bank benchmark.

For instance, querying the interest rate for Australia would yield a response like this:

{"central_bank_rates": [{"central_bank": "Australian Central Bank", "country": "Australia", "rate_pct": 4.35, "last_updated": "11-08-2023"}], "non_central_bank_rates": []}

The response fields include:

• central_bank_rates: An array containing the interest rates set by the central bank.
• central_bank: The name of the central bank.
• country: The country associated with the central bank.
• rate_pct: The current interest rate percentage.
• last_updated: The date when the rate was last updated.
• non_central_bank_rates: An array for any additional benchmark rates.

This feature is essential for financial analysts and businesses that need to stay updated on global interest rates to make informed investment decisions.
