{"openapi":"3.1.0","info":{"title":"Bitcoin Blockchain API","version":"1.0.0","description":"The Bitcoin blockchain as an API, powered by mempool.space. Get live transaction-fee estimates in sat/vB (fastest, 30-minute, 1-hour, economy and minimum) plus a projection of the next mempool blocks, inspect the current mempool size and fee histogram, list recent blocks with their mining pool, size and fees, look up any block by height or hash, check any Bitcoin address for its confirmed balance, total received/sent and recent transactions, fetch any transaction with its inputs, outputs, fee and confirmation status, read the current difficulty adjustment and network hashrate, and get the live BTC price in major currencies. Every amount is in satoshis. Perfect for wallets and fee estimators, block explorers, address and payment monitoring, on-chain dashboards and analytics, and Bitcoin bots. No accounts, no upstream key. For coin market prices use the Crypto API and for DeFi TVL the DeFi API.","contact":{"name":"PremiumApi","url":"https://www.oanor.com/by/premiumapi"}},"servers":[{"url":"https://api.oanor.com/bitcoin-api","description":"oanor
