{"openapi":"3.1.0","info":{"title":"Dash On-Chain API","version":"1.0.0","description":"Live on-chain data from the Dash (DASH) blockchain — a payments-focused cryptocurrency — via the public Dash Insight explorer, clean JSON and no cache. Dash uses X11 proof-of-work plus a second tier of collateralised masternodes that power InstantSend (near-instant locked payments) and ChainLocks, and an on-chain treasury that funds proposals. Read the chain state (block height, difficulty, peer connections, protocol version and relay fee); fetch a block by height or hash; look up an address's DASH balance, total received and sent and transaction count; or resolve a transaction's block, value, fee, input/output counts and its InstantSend lock status. Read live from Dash, nothing stored. This is Dash's own X11, masternode-tier and InstantSend ledger — distinct from the Bitcoin, Decred, Ergo, Nervos and other on-chain APIs and from price feeds.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/dash-api","description":"oanor
