A Complete Guide On Cryptocurrency Development

The spread of the Internet and the development of technology every second have opened new doors to people’s lives. Especially in terms of investment, there have been great developments. Today, standardized foreign exchange and gold investments have started to give way to cryptocurrencies, which are virtual currencies. Cryptocurrencies are created every minute around the world and they serve their investors on various exchanges.

Cryptocurrency trading applications are increasing day by day. These applications, where millions of people simultaneously trade high-volume cryptocurrencies, generally use services that provide Real-time Crypto Currency Exchange Rates API services.

What is Coinlayer API

Serving the Crypto Currency Exchange API, Coinlayer API provides accurate exchange rate data for more than 385 cryptocurrencies in real time. Crypto data is collected from some of the largest cryptocurrency exchanges, requested using HTTP GET and returned in simple JSON format. It has aimed to maximize the availability, consistency and reliability of the crypto data returned by the coin layer API, thanks to an improved fallback algorithm.

The main reason why it is one of the most popular services in the field of coins is that it instantly provides up-to-date crypto exchange rate data for more than 385 cryptocurrencies collected from more than 25 exchanges.

The Coinlayer API not only transmits the most up-to-date data of hundreds of cryptocurrencies to its users in milliseconds, but also provides historical data to its users with its historical data service, allowing them to make analysis and statistics.

The 6 services provided by Coinlayer API are as follows.

  • Live Data: Query the API for the latest available exchange rate data.
  • Historical Data: Look up crypto rates for a specific date.
  • Conversion Endpoint: Convert amounts between cryptocurrencies and target currencies.
  • Time Frame Data: Query the API for crypto data in a specific period.
  • Change Data: Retrieve data about rate fluctuation in a specific period.
  • List Endpoint: Retrieve a list of all available cryptocurrencies and target currencies.

Testing Coinlayer API services with  Python Programming Language

Before proceeding with the testing of the Coinlayer API, a suitable package must be selected and registered on the coinlayer API website and an API key must be obtained to use this service.
