Band Protocol

aid: band-protocol
name: Band Protocol
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).
