## 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 runeswap-bitcoin-transaction-address-query-6f9f362f -d '<json body>'
```

Example prompt: Can you look up Bitcoin transaction abc123def456... and check what's going on with address bc1qxy2kgdygjrsqtzq2n0yrf2493p83kkfjhx0wlh on RuneSwap?

## When to prefer this

Use this endpoint when you need to verify or look up a specific Bitcoin transaction or address on-demand, particularly within the RuneSwap ecosystem which also supports Bitcoin Ordinals and Rune operations. Prefer this over generic blockchain explorers when already using the RuneSwap platform for Rune minting or airdrop activity.

- Invalid or malformed Bitcoin address returns an error
