## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability bitcoin-address-balance-confirmed-unconfirmed-79e27fc6 -d '<json body>'
```

Example prompt: What's the current Bitcoin balance — both confirmed and unconfirmed — for address bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call lookup of both confirmed and unconfirmed BTC balances for a specific Bitcoin address without setting up your own node or maintaining an API key subscription. It is ideal for agents that need on-demand balance checks as part of payment verification workflows, audit tasks, or wallet monitoring — especially in x402-enabled micropayment environments.

## Known failure modes

- Invalid or malformed Bitcoin address returns an error or empty result
- Network timeout if the upstream Bitcoin node is unresponsive
- Address with no transaction history may return zero balances
- Payment failure (x402 protocol) prevents the query from executing
- Rate limiting or quota exceeded on the operator network
