Blockchain allows data providers and consumers to trade information directly in a single open system, rather than subscribing to dozens of centralized services around the world and writing their software to communicate with each API. Read this best blockchain api tutorial to learn how to use it for your specific needs.

An API (Application Programming Interface) is a description of the methods (classes, procedures, functions, structures, or constants) that a single computer program can use to interact with another program. It is usually included in the description of any Internet protocol (such as RFCS), software framework, or standard call to an operating system function. It is usually implemented by a separate software library or operating system service. Developers often use blockchain apis to write various applications.

An API defines the functionality provided by a program (module, library) and allows abstraction from how that functionality is implemented. Software components interact with each other through apis. In this case, components typically form a hierarchy: higher-level components use apis from lower-level components, which in turn use apis from even lower-level components. The protocol for data transmission over the Internet is built on this principle.

The standard protocol stack (OSI network model) consists of 7 layers (from the physical bit transport layer to the application protocol layer, similar to the HTTP and IMAP protocols). Each level uses the capabilities of the previous underlying data transfer level and provides the necessary capabilities for the next level of coverage.

Note: The concept of protocol is similar to the concept of API. Both are abstractions of functionality, except that the protocol deals with data transfer, while the API is related to the interaction of the application.

Blockchain API varieties

The development of blockchain software usually involves various difficult parts. One of the most important is creating a blockchain API interface. Some projects help users and developers by providing the following API services:

Incredibly easy way for websites to receive payment in Bitcoin. This service is completely secure and is ideal for business or personal use:

Blockchain linked wallet service.

An API for sending and receiving payments from a blockchain wallet.

JSON for each block and transaction data request.

Simple Blockchain API for Requests: A simple API for querying the text format of blockchain data.

Web socket: A streaming socket with low latency that provides data for new blocks and transactions.

Let's start with the Blockchain Wallet API review. The blockchain Wallet API provides a simple interface. To use this API, you need to start a small local service that manages the wallet. Your application interacts with this service locally through HTTP API calls.
