APRO is a data oracle protocol that provides real-world information to blockchain networks. The protocol is designed to supply data for a range of applications within the digital asset ecosystem, including those involving real-world assets (RWA), artificial intelligence (AI), prediction markets, and decentralized finance (DeFi). APRO's infrastructure integrates machine learning models to assist in data validation and sourcing.

APRO is integrated with over 40 blockchain networks, enabling smart contracts on these platforms to access its data. The protocol maintains more than 1,400 individual data feeds, which are used by applications for functions such as asset pricing, settlement of prediction market contracts, and triggering specific protocol actions.

The development of the APRO protocol is supported by several investment firms. These include Polychain Capital, Franklin Templeton, and YZi Labs. These entities have provided funding to support the protocol's research, development, and ecosystem growth.
