Airnode is an oracle node and API blockchain gateway that is readily deployed by API providers who want to engage in the API3 blockchain protocol and put their data feeds on-chain.

What Is Airnode?

The decentralized web, or Web 3.0, is the internet’s next incarnation. It revolutionizes how the world transfers assets with the use of blockchain. 
Since the advent of the internet, Web 3.0 has had the most significant growth potential for organizations. Airnode offers a simple way to get started with this technology. It is an open-source Web3-API middleware that allows any web API to be easily connected to a blockchain application.
Decentralization is the core of Web3 security that has become an issue for API providers. Smart contracts are unable to link directly to APIs that provide access to real-world data and services. Oracles act as a bridge between blockchains and the real world. In this game, Airnode works as the API economy’s Web3 oracle solution. It is a maintenance-free, serverless platform that links any web API to any blockchain application. Traditional oracles require the interference of a third party. Airnode eliminates the need for a third-party intermediary.
For connecting firms to the blockchain, third-party oracles demand substantial fees. With Airnode, any business can directly link to blockchain apps while keeping 100% revenue. It is a free and open-source platform that ensures that a user’s connectivity to the blockchain always remains under their control.
