Google provides a variety of APIs that can be used to retrieve currency exchange rates. One popular method is the Google Finance API, which allows developers to retrieve real-time or historical currency exchange rates. To use this API, you will need to sign up for a free API key from the Google Cloud Console. Once you have your key, you can use it to request the API in the form of a URL, specifying the currencies you wish to exchange and the date or time range for which you want to retrieve the exchange rate. You can then use the returned data in your application or website to display currency exchange rates to your users.
What you need to access Google API for Currency Exchange Rates
Before you can use the Google API to get currency foreign exchange rates API, you will need to create a project in the Google Cloud Console. Once you have created a project, you will need to enable the Google Finance API for that project. To do this, navigate to the “APIs & Services” dashboard, and search for “Google Finance API”. Once you have found the API, click on the “Enable” button to activate it.
Once the Google Finance API is enabled, you will need to create credentials to access the API. To create credentials, navigate to the “Credentials” tab and click on the “Create credentials” button. Select “API key” as the type of credentials you want to create. This will generate an API key that you will use to access the API.
With your API key and project set up, you can now start using the Google API to get currency exchange rates. To do this, you will need to make a GET request to the API endpoint. The endpoint for getting currency exchange rates is “https://finance.google.com/finance/converter“. You will need to pass in the from and to currencies, and the amount you want to convert. The API will return the exchange rate and the converted amount.
First, you will need to get an API key from Google. To do this, you will need to create a project in the Google Cloud Console and enable the Google Finance API for that project. Once you have done this, you will be able to generate an API key that can be used to access the API.
Next, you will need to make a request to the API using the API key and the desired currency codes. The API supports multiple formats for the request, including JSON and XML. You can use any programming language that supports HTTP requests to make the request, such as Python, Java, or C#.
The API will return the current exchange rate for the requested currency pair. For example, if you request the exchange rate for USD to EUR, the API will return the current exchange rate for that pair. You can also specify a date in the past to get the exchange rate for that specific date.
Once you have the exchange rate, you can use it in your application to calculate the equivalent amount in the other currency. For example, if you are building an e-commerce website and want to show prices in multiple currencies, you can use the exchange rate to convert the prices to the desired currency.
It’s worth noting that Google Finance API is deprecated and no longer available for use. However, there are several other exchange rate APIs available to use, like Open Exchange Rates, Currency Layer, or Fixer.io. They provide similar functionality as the Google Finance API and you can use them in the same way.
To use these other APIs, you’ll need to sign up for an account and get an API key. Once you have the key, you can request the API using the desired currency codes. For example, using Open Exchange Rates API, you can make a GET request to the following endpoint: https://openexchangerates.org/api/latest.json?app_id=YOUR_APP_ID
This endpoint returns the latest exchange rates for all currencies in JSON format. You can also specify the base currency, and historical exchange rates by requesting a different endpoint. It’s also worth noting that these APIs usually have usage limits, so be sure to check their documentation to see how many requests you can make per month or per day.
In conclusion, using Google API to get free currency API exchange rates is a simple and efficient way to access real-time data for your financial or business needs. By following the steps outlined in this guide, you can easily access the API and retrieve the information you need. Additionally, you can also customize your requests to retrieve specific data and even set up automatic updates to stay on top of currency fluctuations. Overall, Google API is a valuable tool for anyone looking to stay informed and make informed decisions when it comes to currency exchange rates.
