How do the JSON and Object and description table of latest exchange rates API created by Fixer function?

In this article, I will provide an overview of the object table and JSON output of Fixer's latest exchange rates API. As a developer, understanding the structure and format of the data you receive from APIs is crucial for utilizing them effectively. Fixer provides a simple and user-friendly API that allows developers to access real-time and historical exchange rate data in a variety of formats, including object tables and JSON. By understanding the object table and JSON output, you can make the most out of Fixer's API and build applications that rely on accurate and up-to-date currency exchange rates.

API Object Table

1. success: This object returns a boolean value indicating whether the API request was successful or not. If the request was successful, the value of success will be true, and if there was an error in the request, the value of success will be false.

2. timestamp: This object returns the exact date and time when the exchange rates were collected in UNIX time format. The UNIX timestamp represents the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC.

3. base: This object returns the three-letter currency code of the base currency used for the API request. The base currency is the currency against which all other currencies are compared in the exchange rate data.

4. rates: This object returns the exchange rate data for the currencies that were requested in the API call. The rates object contains key-value pairs, where the key is the three-letter currency code for the currency being converted to, and the value is the exchange rate from the base currency to that currency. For example, if the base currency is USD and the requested currency is EUR, the value in the rates object for the key "EUR" would be the current exchange rate from USD to EUR.

The information in the table is useful for developers who are building applications that require real-time and accurate exchange rate data. By using the objects returned by the Fixer latest exchange rates API, developers can programmatically access currency exchange rates and use this data in their applications to perform currency conversions, financial calculations, and more. Understanding the structure and format of the data returned by the API is essential for developers to extract the relevant information from the response and incorporate it into their applications effectively. The success object allows developers to check the status of the request and take appropriate action in case of errors. The timestamp object enables developers to know when the exchange rates were last updated, while the base object lets them know the currency against which all other currencies are compared. The rates object is especially useful as it contains the actual exchange rate data, which can be used in applications to perform currency conversions and other financial calculations.

Explaining the JSON output

The JSON output is the response from an API request for the latest exchange rates, with the base currency being USD. The response contains five key-value pairs, where the success key has a boolean value of true, indicating that the request was successful. The timestamp key has a Unix timestamp value of 1519296206, representing the date and time the exchange rates were collected. The base key has the value "USD", indicating that the exchange rates are based on USD. The date key has the value "2022-10-24", indicating the date for which the exchange rates are applicable. Finally, the rates key has a dictionary value containing the exchange rate data for the requested currencies. In this case, the dictionary contains exchange rates for GBP, JPY, and EUR, with their respective exchange rates of 0.72007, 107.346001, and 0.813399 relative to the base currency (USD). This JSON output can be used by developers to programmatically access the exchange rates and incorporate them into their applications.

{
"success": true,
"timestamp": 1519296206,
"base": "USD",
"date": "2022-10-24",
"rates": {
"GBP": 0.72007,
"JPY": 107.346001,
"EUR": 0.813399,
}
}
