(Terms and Conditions, Article 17, Paragraph 8) ### ※ Additional Digital Asset \~\~API3 (API3)\~\~ > API3 is a project building a decentralized API (Application Programming Interface) for Web 3.0. Decentralized applications (dApps) should be able to access web APIs that provide services interacting with the real world. However, most APIs cannot be integrated with dApps through on-chain connections. While existing intermediary-based interface solutions are centralized, insecure, and expensive, API3 aims to replace these through a decentralized platform. API3 seeks to further evolve the concept of APIs to meet the strict decentralization requirements of Web 3.0 without the need for third-party intermediaries. > Website: [Official API3 Website](https://api3.org/) > X (formerly Twitter): [Official API3 X](https://x.com/Api3DAO) > Whitepaper: [Official API3 Whitepaper](https://drive.google.com/file/d/1b8QsGPCJJC1pQOcg83-knD1IAOIgCtZZ/view) ✽ If this digital asset cannot be viewed on PC, please refresh (F5) and check again. ✽ If this digital asset cannot be viewed on the Upbit App, please click ‘More’ > ‘Screen Settings’ > ‘Refresh Coin Information’ and check again.
