Everything You Need To Know About APIs

APIs help developers integrate added value, help users access important services, and help dApps build and improve. Learn about what are APIs, explore 31 API dApps on BNB Chain, and and learn how to avoid risky APIs.


What are APIs?

APIs stand for Application Programming Interfaces and are software intermediaries that enable two or more applications to interact or communicate with each other. APIs can be used to access and share data related to the stock market, the weather, the prices of crypto assets, making payments using Web3 wallets, and more. 


What are API dApps?

API dApps are Application Programming Interfaces built for decentralized applications built on the blockchain. APIs for dApps are similar to APIs for traditional apps, except the former is available for all developers to build on, while the latter is available to an exclusive group of developers. 


A few examples of API dApps include full-suite data network solution (PARSIQ), AI smart contract generator and AI NFT generator (ChainGPT), distributed nodes infrastructure (Ankr), Credential Oracle Engine API (Galxe), security infrastructure for Web3 (Go+), blockchain explorer and analytics platform for BNB Greenfield (GreenfieldScan), total crypto intelligence (Arkham) and more. 


31 APIs on BNB Chain

The list of APIs dApps on BNB Chain was selected based on the 35 listed APIs on DappBay as on 2 August 2023. Out of the 35 listed API dApps, 4 dApps were listed in Red Alarm because of risks associated with those dApps and eliminated from this list. Other APIs not listed on DappBay have not been included in this list. 

The remaining list of 31 API dApps is listed below according to 10 categories including cybersecurity and intelligence, data, infrastructure, digital payments, gaming, NFTs and marketplaces, communication, blockchain explorers, identity, and others. A dApp may fall into more than one API category but has been listed under one main category for simplicity. The dApps under each category are listed in alphabetical order.
