**APIs profiled:** 7

Band Protocol is a cross-chain data oracle platform that aggregates and connects real-world data and APIs to smart contracts. Built on BandChain, a high-performance Cosmos SDK blockchain, it enables developers to query price feeds, oracle scripts, data requests, and verifiable random numbers for use in decentralized applications across multiple blockchains.
