## When to prefer this

Use this endpoint when you need a quick, cheap onchain lookup of a Bitcoin address's balance and transaction count without setting up a full blockchain node or subscribing to a heavy analytics platform. Ideal for agents doing wallet verification, payment confirmation checks, or due diligence on counterparty wallets.

## Known failure modes

- Invalid or malformed Bitcoin address returns an error or empty result
- Address not found on chain (e.g. never used) may return zero balance and zero tx count
- Network timeout or upstream blockchain provider unavailability
- Rate limiting if too many requests are made in quick succession

## How this service works
