Top 11 Blockchain APIs for Web Developers

With online stores all over the world continuing to adopt Bitcoin and cryptocurrency payments, knowing which dedicated Blockchain API to use is important.

Blockchain APIs allow e-commerce owners and stores to save time and money in the developing of payment systems from scratch and this allows them to focus on more significant and essential things to improve their service.

Here are top 10 API blockchain providers

Blockstrap API

Blockstrap API was introduced by Neurowave to serve web-developers and programmers. It helps them to create cryptocurrency-related web-applications that are compatible with HTML5 when working with Bitcoin and other digital assets.

It accepts data from and is compatible with SoChain, Hello!, Block and Blockr APIs sources in addition to using its own data source.

Neurowave does help organizations to integrate existing legacy systems with new distributed ledger technology when a company wants to use blockchain in its business. For instance, they work with large central banks, national regulators, telecommunication providers and licensed equity crowdfunding institutions in Malaysia and Singapore. They also provide training, consulting and hosting.

Chain API

Chain Core is based on Chain Protocol and is an enterprise-grade software for issuing and transferring financial assets on blockchain. With Chain Core, institutions can launch and operate a network on the blockchain or connect to already existing networks.

The transfer is done while maintaining the governance standards, scalability, and privacy required in financial markets. It allows for management and transfer of different types of assets on the blockchain including currencies, securities, derivatives, gift cards, and loyalty points.

For instance, banks and other financial institutions can employ this to move money internationally more quickly, transfer securities directly between asset managers, serve as a secure ledger for tracking assets across distributed divisions in a large organization, enabling next-generation mobile banking solution, creating loyalty points system for brands, issuing digital cards on a network that supports multiple wallets and creating automated insurance contracts.

It can also help those issuing central bank currency digitally and improve payment systems in a country.

The developer edition is available for free.

Tierion Hash API

 Tierion Hash API Documentation from Tierion can create up to 100 records per second free of charge. It collects data from web and mobile applications using built-in REST API and HTML-forms. With Chainpoint, authenticity of data relating to transactions can be verified, including creation time because that data's hash is attached to blockchain unit by Chainpoint.

It can also integrate with many services including Salesforce, Mailchimp, Gmail, Slack, etc.

Factom Alpha

Factom software integrates with a company's existing software to allow for sharing, auditing and exchanging sensitive information secured by blockchain technology.

This prevents lost documents, reducing audit time and preventing costly disputes. Each user retains their own documents, files and data securely.

It lets developers build custom applications under collaborative environments. It also allows for use of data to make better decisions.

With their latest addition dLoc, governments, banks, hospitals, and universities that issue documents, including birth certificates, land titles, and medical records can use blockchain to authenticate and secure the documents.

Lenders can get blockchain based document audit solutions for loan reviews for compliance.

Coinbase blockchain API

Coinbase blockchain API provides REST API to integrate  bitcoin, bitcoin cash, litecoin and ethereum payments into your business or application. 

Your customers receive authorization notices when they make a transaction using their cryptocurrency reserves. Coinbase functionality allows creating a wallet, purchasing, selling, sending, receiving and storing the above-mentioned cryptocurrency.

Developers get a colossal number of useful libraries and a development toolkit.

Blockchain API

Blockchain API is a free tool for developers needing to integrate Bitcoin cryptocurrency payment functionality on their apps and website.

Information is available in JSON format and this simplifies processing by customer. Customers can access Bitcoins directly on their e-wallet account thus needing no separate storage.

Bitcore API

Bitcore API allows for building of Bitcoin and blockchain-based applications.

Written in JavaScript, this Bitcoin API is ideal for P2P networks (those not using dedicated services and whose nodes serves both as customer and server).

Its speed exceeds that of built on centralized web architectures by 20 times. Therefore, it is a great solution for networks hoping to scale in the future.

Furthermore, the API has Insight blockchain explorer featuring REST and WebSocket API interfaces. This makes it fit for programmers who want to develop their “turnkey” electronic wallets or similar solutions that would involve quite complex server requests from blockchains.

Colu SDK

The Colu API/SDK is used for issuing digital assets on top of Bitcoin. It can be used to issue fiat on the blockchain, maximize privacy, deploy systems in the cloud (a framework for cloud based money) or internally and integrate Bitcoin standards.

The basic functionality includes cryptocurrency transfers, transaction encryption, BIP44 usage and search and reading of asset metadata.

The Colu blockchain API is suitable for those developers and programmers using other languages different from Node.js. This avoids technical conflicts between existing platform and implemented interface.

User wallets are protected with private keys for monetary asset management.

Gem

Gem is a HTTP blockchain API that allows integration of fully functional Bitcoin wallets in enterprise systems. Users can create as many wallets as they want. It also provides multi-signature authorization, multi-factor authentication, and real-time monitoring for added security. 

It provides scalability in addition to storage, encryption and copy of cryptocurrency for all your customers.

It encrypts Bitcoins and sends them to the server without storing them.

BlockCypher

BlockCypher offers several solutions (RESTful JSON APIs) such as Ethereum Blockchain API and Bitcoin Blockchain API for developers. These provide access in accordance with HTTP and HTTPS protocols from the api.blockcypher.com domain.

The limitations include up to 5 units/sec or up to 600 requests/hour; and WebHooks and WebSockets requests – up to 600 requests/hour.

Other features include built-in microtransactions for internal purchases and on the platform and payments readdressing.

ChromaNode API

Distributed by ChromaWay, ChromaNode API uses JavaScript and uses the PostgreSQL database to store transactional data. It employs the WebSocket protocol to transfer data over TCP connections.

It assigns a personal index to blockchain’s units to facilitate sending cryptocurrency from customer to e-commerce. It only sends the chain to the server only at this time. The server will receive transaction messages with confirmation about their completion.

It allows for customization of the application's architecture as the business grows, distributing it among several servers. This means you can increase the number of servers without employing another blockchain API.
