How do the Object table and JSON output of Fixer historical time-series exchange rates API work?

In this article, I will provide a clear and concise explanation of the object table and JSON output of the Fixer historical time-series exchange rates API. As a programmer, you may already be familiar with the concept of object tables and JSON, but understanding the specific implementation of these data structures in the context of the Fixer API can be crucial to effectively utilizing the data it provides. By the end of this article, you should have a solid understanding of the object table and JSON output of the Fixer historical time-series exchange rates API, which will help you make the most of this valuable resource in your programming projects.

Object and description table

ObjectsDescription
successReturns true or false depending on whether or not your API request has succeeded.
timeseriesReturns true if a request to the timeseries endpoint is made.
start_dateThe start date of your time frame.
end_dateThe end date of your time frame.
baseReturns the three-letter currency code of the base currency used for this request.
ratesReturns exchange rate data for the currencies you have requested.
  1. success: This object returns a boolean value indicating whether or not the API request was successful. If the value is true, the request was successful. If the value is false, there was an error with the request.

  2. timeseries: This object returns a boolean value indicating whether or not a request was made to the timeseries endpoint. If the value is true, the request was made to the timeseries endpoint. If the value is false, a request was not made to the timeseries endpoint.

  3. start_date: This object returns the start date of the time frame for which the exchange rate data is being requested. The start date is provided in the format YYYY-MM-DD.

  4. end_date: This object returns the end date of the time frame for which the exchange rate data is being requested. The end date is provided in the format YYYY-MM-DD.

  5. base: This object returns the three-letter currency code of the base currency used for the request. This currency code is used as the reference point for all exchange rate data provided in the response.

  6. rates: This object returns the exchange rate data for the currencies that were requested. The exchange rate data is provided as key-value pairs, where the key is the three-letter currency code for the currency being exchanged, and the value is the exchange rate. The exchange rates are provided in relation to the base currency provided in the request.

The information in the table provides valuable insight into the structure and contents of the Fixer historical time-series exchange rates API. As a programmer, understanding the objects returned by an API is crucial to effectively utilizing the data it provides. The objects in the table help to clarify the specific information that can be retrieved from the API, such as exchange rate data, time frame data, and success status. This information can be used to build more powerful and flexible programs that rely on exchange rate data. In addition, by providing a clear description of each object, the table makes it easier for programmers to use the API and integrate its functionality into their own projects.

JSON explained

The JSON output below provides exchange rate data for the Euro (EUR) currency against three other currencies (USD, AUD, and CAD) for a specified time frame, from May 1, 2012, to May 3, 2012. The "success" and "timeseries" objects indicate that the API request was successful and that a request was made to the timeseries endpoint. The "start_date" and "end_date" objects specify the start and end dates of the time frame, respectively. The "base" object indicates that the exchange rates are provided in relation to the Euro currency. The "rates" object provides the exchange rate data for each day in the specified time frame. The exchange rate data is organized as nested key-value pairs, with each date in the time frame serving as the primary key, and the exchange rates against each of the three currencies provided as secondary keys with their respective values. The ellipsis at the end of the "rates" object indicates that there is more exchange rate data provided, but it has been truncated for brevity.
