This article mainly introduces how to better use blockchain API related knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe that everyone after reading this article on how to better use blockchain API will have a harvest, let's take a look.

API (Application programming Interface) is a description of 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 RFC), a software framework, or a standard call to operating system functions. It is usually implemented by a separate software library or operating system service. Developers often use blockchain API to write various applications.

API defines the functionality provided by the program (module, library) and allows it to be abstracted from the way the function is implemented. Software components interact with each other through API. In this case, components usually form a hierarchy: high-level components use the API of low-level components, which in turn use the API of even lower-level components. The protocol for data transmission over the Internet is based on this principle.

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

Note: the concept of protocol is similar to that of API. Both are abstractions of functionality, except that the protocol involves data transfer and API is related to the interaction of the application.

Block chain API varieties

The development of block chain software usually includes all kinds of difficult parts. The most important of these is to create a blockchain API interface. Some projects help users and developers by providing the following API services:

An incredibly easy way for websites to receive bitcoin payments. This service is completely secure and is ideal for business or personal use:

Block chain linked wallet service.

API used to send and receive payments from blockchain wallets.

JSON for each block and data request for the transaction.

Simple block chain API for request: a simple API in text format for querying block chain data.

Web sockets: streaming sockets with low latency to provide data for new blocks and transactions.

Let's start with the blockchain Wallet API comments. Blockchain Wallet API provides a simple interface. To use this API, you need to start a small local service responsible for managing wallets. Your application interacts with this service locally through HTTP API calls.

Now, you can transfer bitcoin from the new blockchain wallet API. All transactions are worth 0.0001 BTC miners' fees. This is what it looks like in PHP:
