How do the JSON and Object and description table of currency conversion API created by Fixer function?

In this article, I will be clarifying the object table and JSON output specifically of Fixer currency conversion API. For those with programming knowledge, understanding the structure and content of the data returned by an API is critical for leveraging the data effectively. Fixer currency conversion API provides an object table and JSON output which may require a bit of explanation to fully comprehend. I will provide a clear and concise breakdown of these data structures, highlighting their differences and what kind of information can be obtained from each. With this knowledge, you will have a better understanding of how to parse and utilize the data returned by Fixer currency conversion API to suit your specific needs.

Object and Description of API

• query > from: A string that represents the three-letter currency code of the currency being converted from. This object is used to specify the currency that you are converting from.

• query > to: A string that represents the three-letter currency code of the currency being converted to. This object is used to specify the currency that you are converting to.

• query > amount: A number that represents the amount being converted. This object is used to specify the amount of the currency being converted.

• info > timestamp: A number that represents the Unix timestamp of the exchange rate data used in the conversion. This object is used to specify the exact time and date that the exchange rate data was collected.

• info > rate: A number that represents the exchange rate used in the conversion. This object is used to specify the exchange rate that was used to calculate the conversion.

• historical: A boolean value that indicates whether the conversion used historical exchange rate data. A value of true indicates that historical exchange rate data was used, while a value of false indicates that current exchange rate data was used.

• date: A string that represents the date that the exchange rate data was collected. This object is used to specify the exact date that the exchange rate data was collected.

• result: A number that represents the result of the currency conversion. This object is used to specify the final converted amount of the currency being converted.

The given JSON output represents the result of a currency conversion using the Fixer API, converting 25 British Pounds (GBP) to Japanese Yen (JPY) as of February 22nd, 2018. The object contains several key-value pairs, with each key representing a different piece of information about the conversion. The "success" key indicates whether the API request was successful, with a value of "true" indicating success. The "query" key provides information about the source currency ("from"), the target currency ("to"), and the amount being converted. The "info" key provides additional information about the exchange rate used in the conversion, including the timestamp of the exchange rate data and the actual exchange rate ("rate"). The "historical" key indicates whether historical rates were used for the conversion, while the "date" key provides the date on which the exchange rate data was collected. Finally, the "result" key provides the final converted amount of JPY that corresponds to the original 25 GBP amount.
