What is an Airnode?

Airnode is an open-source Web3 API middleware. It is a kind of application software that makes it simple for web APIs to connect to blockchain applications. The decentralized internet, which is considered the next phase of network growth, presents challenges for many API providers as they try to adapt their services to it. An example of an Oracle solution for Web 3.0 is Airnode. The API doesn't need upkeep and doesn't need a server. It can connect all online APIs and blockchain apps. In contrast to conventional Oracle solutions, Airnode does not need outside influence.
