Frequently asked questions

How are API3's data feeds different?

API3's data feeds, known as dAPIs, are different because they source their data directly from high-quality data providers without relying on third-party middlemen.

How can API3 support gaming on the blockchain?

Gaming applications on the blockchain often require continuous random number generation to keep operations unpredictable and exciting for players. API3's tamper-proof randomness generation can be utilized by game developers to ensure fair odds in games of chance, where financial incentives are rewarded for correct wagers.

What is Airnode and how does it connect APIs to blockchain applications?

Airnode is an open-source Web3 middleware that connects any web API directly to any blockchain application. It serves as a provider-focused oracle solution for connecting real-world data to blockchain applications. Airnode operates as an API gateway, allowing smart contracts to call off-chain APIs and receive data from them on the blockchain without the need for third-party middlemen. It is compatible with most EVM-based blockchains and is free to use under the MIT License. Airnode does not require handling cryptocurrencies as the requester pays for the blockchain gas fees.
