Blockstream.info Esplora API — the most recent Bitcoin transactions touching one address, covering both unconfirmed mempool entries and confirmed ones, on mainnet or testnet. Each transaction returns its txid, inputs and outputs with values and scripts, fee, size and confirmation status with block height. Answers what this Bitcoin address has sent or received lately.
