12 Cryptocurrency APIs for Data Scientists/ Developers

The demand for crypto projects tends to increase with time. Let’s check out some of the best crypto APIs.

Before we get to know about crypto APIs, let’s have a look at APIs first. An Application Programming Interface (API) is a software solution that allows the interaction of two or more applications. APIs are commonly used for room booking, food ordering, payment processing, and more.

Cryptocurrency APIs also function like the APIs mentioned above. The main difference is that crypto APIs interact with various crypto markets and exchanges. First, it’s essential to know about data collection to understand APIs clearly.

Data Collection and Its Importance

Data collection is the backbone of every API. Simply put, data collection involves a step-by-step process of gathering information related to a specific subject. Here, in the case of crypto APIs, the collected data is related to various crypto projects and currencies associated with them.

APIs collect data from credible sources, process it, and store it. Later, the stored data is analyzed and organized according to the individual’s or organization’s use case.

Manual collection of massive data is practically impossible, so APIs have different methods for collecting relevant data. Keeping that in mind, let’s check out some alternative ways of data collection:

• Data importing: Data import is simply a process of copying data from one program or source to another. Data scientists use various methods to import necessary data from a database, file, or other sources.

• Downloading data from a resource: In the case of data download, a bulk quantity of data is stored on a storage device as a permanent copy. This stored data is later used by data developers or scientists for a prolonged period.

Benefits of Web APIs

You might think, but how will I benefit from crypto web APIs? All right, let’s shed some light on it.

•  Whether you’re a crypto trader, developer, analyst, or enthusiast, APIs help smoothen your crypto journey.
• If you are a developer, you can use crypto APIs to build a trading bot, business solutions, or payment platforms.

• Similarly, suppose you are someone who trades or invests in cryptocurrencies. You can also use crypto APIs to track your portfolio, place buy or sell orders, and much more. Apart from that, APIs allow you to analyze charts, check live crypto prices, or set multiple price alerts.
• APIs are crucial in improving and increasing productivity by enhancing fast and more straightforward software development. For instance, developers don’t have to waste time and energy building from scratch.
• Software development costs are significantly reduced as APIs take care of important data imports and downloads.  

Having discussed APIs and their relevance in the crypto space, let’s dive in and check the best crypto APIs.

CoinGecko API

We’ll begin the list with CoinGecko API, as it’s one of the most budget-friendly crypto APIs. If you want to build a project on a tight budget, you can consider CoinGecko API.

CoinGecko API provides access to essential crypto data equally beneficial for crypto developers, traders, and scientists.
