## 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 agent-data-tools-bitcoin-address-lookup-736ba01a
```

Example prompt: What's the current BTC balance and total number of transactions for the Bitcoin address bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh?

## When to prefer this

Choose this endpoint when you need live on-chain Bitcoin address data (balance, transaction history) without setting up an API key or account — ideal for agents that need pay-per-call blockchain lookups billed in USDC on Base via x402, supporting legacy (1...), P2SH (3...), and native SegWit (bc1...) address formats.

## Known failure modes

- Invalid or malformed Bitcoin address returns an error response
- Address not found on mainnet (e.g. testnet address) may return zero balances or an error
- Network timeouts from upstream blockchain data provider
- Payment failure via x402 if insufficient USDC balance on Base
- Rate limiting or worker errors from Cloudflare Workers host

## How this service works

Pay-per-call tools for AI agents: web page text extraction and summaries, screenshots, image generation, speech-to-text, image description, domain and email-auth intelligence, and live Base token and wallet lookups. No account or API key; pay per request in USDC on Base via x402.

## Output

Returns a JSON object containing the address, network identifier ('bitcoin'), current balance in BTC and satoshis, pending satoshis, total BTC sent, total BTC received, confirmed transaction count, and pending transaction count.
