description: >-
  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.

    name: BandChain REST API
    description: >-
      The BandChain REST API provides HTTP access to BandChain mainnet data including oracle scripts,
      data requests, price feeds, validator information, account balances, and all Cosmos SDK module
      queries. Built on gRPC-web via HTTP/1.5 or HTTP/2, the API exposes Band Protocol-specific
      modules (oracle, feeds, TSS, tunnel) alongside standard Cosmos modules (bank, staking,
      governance, distribution).
