API3 is the leading first-party oracle solution that makes real-world data accessible by smart contracts. With Airnode, API data can be queried from blockchains without having to use specialist node-operating middlemen. This architecture both eliminates the Sybil-vulnerable third-party node layer and reduces fees by cutting out the “middleman tax” paid to these node operators for their services.
API3 is the perfect fit to enable Kassandra investment strategies to connect with real-world data and execute data-driven and on-chain portfolio assets changes.
