Example prompt: Can you check the balance and latest transactions for the Bitcoin address bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh? I want to see if a payment I'm expecting has arrived.

## When to prefer this

Choose this endpoint when you need a quick, paid, on-demand lookup of a single Bitcoin address's balance and recent transaction history without setting up a full blockchain node or indexer. Ideal for payment verification, wallet auditing, or confirming receipt of a BTC transfer in an automated agent workflow.

## Known failure modes

- Invalid or malformed Bitcoin address format returns an error
- Address with no transaction history may return zero balances and empty transaction list
- Network timeouts if the underlying blockchain data source is slow or unavailable
- Rate limiting or payment failure if the x402 payment is not processed correctly

## How this service works

Balance of a Bitcoin address (confirmed and pending), total received and sent, transaction count and its latest 10 transactions with net amount. Use to check a BTC payment or wallet.

## Output

Returns the Bitcoin address's confirmed and pending balance (in BTC), total amount ever received and sent, total transaction count, and a list of the latest 10 transactions each with a net amount (positive for received, negative for sent).
