Bitcoin address intelligence API

Resolve a Bitcoin address to balance, total received/sent, transaction count, and a confirmed/unconfirmed split via the keyless mempool.space API, normalized to both sats and BTC. The value-add is folding mempool's chain/mempool stat split into one clean balance sheet, and it opens Bitcoin coverage alongside our EVM endpoints. Answers 'balance of this Bitcoin address', 'total received by this BTC address', 'how many transactions for this wallet', 'is there unconfirmed activity on this address'.
