Bonus: How to Choose the Best Currency Exchange API?
The above are undoubtedly some of the best currency exchange APIs out there. However, every business is different based on its size, budget, and needs. So, when you choose the API, make sure you do it according to your requirements.
Here are some of the criteria to choose a suitable currency exchange API.
Before finalizing the currency exchange API, find out how many currencies it supports; the more, the better. Look at the list and locate if it supports the currency you are dealing with, along with many others that you would deal with in the future.
Many of the above-explained APIs support over a hundred currencies, so you can operate in various markets with ease. It would be best if they support 150+ currencies, including the most important ones like USD, Pound, and Euro. A smaller number of currencies will also do if it has the vital ones and a good set of features.
Another critical aspect of choosing an exchange API is how many data sources it offers. The API works by gathering information from various sources. Hence, choosing an API that can provide humongous data and more data sources is essential.
In addition, find if the data sources are genuine or not because you need accurate, trustworthy data for your business. The provider must offer enough reliable data sources so you can aggregate information and track and measure global trends for your business.
You may look for large banks, financial institutions, and reliable websites as data sources. If you get 10+ data sources, it’s best.
How often the data updates in the API is crucial. The reason is financial markets and value may change at any time, and you need fresh data to run your operations. The best exchange APIs update data within 10-60 seconds, while others may take minutes and hours. If your operations run every day 24/7, you need to choose the one that can update data most frequently.
A good exchange API can provide you with accurate currency information and convert or exchange currencies with speed and security. Thus, choose a reliable currency exchange API and run your business operations smoothly to make more profits.
