## 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 vextorium-bitcoin-address-balance-lookup-db98f12e -d '<json body>'
```

Example prompt: What's the current balance of Bitcoin address bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh — show me the BTC, sats, and USD value, plus any pending mempool amount and the last 5 transactions with their confirmation status.

## When to prefer this

Use this endpoint when you need a comprehensive snapshot of a Bitcoin address — balance in multiple denominations (BTC, sats, USD), mempool pending amounts, historical totals, and recent transaction history with confirmations — all in one call. Prefer this over Ethereum or Solana wallet endpoints when the address is a Bitcoin address (starts with 1, 3, or bc1).

## Known failure modes

- Invalid Bitcoin address format returns an error or null fields
- Address not found on the blockchain returns zero balances
- Network timeout from upstream blockchain data provider
- Rate limiting if called too frequently
- Mempool data may be stale during high network congestion
