Bitcoin Mempool API

Live Bitcoin on-chain and mempool data as an API, built on the open mempool.space dataset — a different layer from market-price feeds. Get recommended transaction fees (sat/vB) for fast, half-hour, hour and economy confirmation, the current mempool state with its fee histogram, the most recent blocks and full block detail by height or hash (size, weight, transaction count, mining pool, reward and fees). Look up any Bitcoin address for its confirmed and unconfirmed balance and transaction counts, or any transaction by id for its inputs, outputs, fee and confirmation status. Track the difficulty-adjustment countdown, mining-pool hashrate share, the network hashrate over time and the current BTC price. Real on-chain data, no key needed upstream. Ideal for wallets, block explorers, fee estimators, mining dashboards and crypto analytics.
