# Xpub Utility

> Native Bitcoin xpub tooling — derive every address from a Bitcoin extended public key (xpub) along with its transfer count.

## Overview

Bitcoin developers regularly need to map an xpub to **every address it derives** — and to know which of those addresses have actually been used. The xpub utility solves that natively.

Pass a Bitcoin extended public key (xpub), and the API returns every derived address with its transfer count. No client-side derivation library required.

## Endpoint

| Endpoint                                                             | Universal path                                         |
| -------------------------------------------------------------------- | ------------------------------------------------------ |
| [Addresses From Xpub](/data-api/bitcoin/utility/addresses-from-xpub) | `GET /v1/chains/bitcoin/wallets/{publicKey}/addresses` |

## Pairing With the Wallet API

The Wallet API endpoints accept either an address or an xpub directly. For most flows you don't need to call the utility endpoint first — the API derives the addresses server-side.

Use the utility endpoint when you need to **enumerate and display** the derived addresses themselves — for example a wallet UI that surfaces "this xpub controls the following addresses," or an analytics pipeline that wants to track each derived address independently.
