# Web3 Data Skill

> Query on-chain data and crypto social intelligence using natural language in Claude Code

## Overview

The **Web3 Data Skill** is a [Claude Code](https://docs.anthropic.com/en/docs/claude-code) skill that covers two Chainbase services:

* **On-chain data** — query token holders, wallet balances, NFT ownership, ENS domains, address labels, transactions, and more across multiple EVM chains via the Chainbase API.
* **Crypto social intelligence** — discover trending crypto narratives, search topics, retrieve Twitter/X mentions, and monitor social signals via [Tops](https://tops.chainbase.com). No API key required.

## Installation

Install the skill via [skills.sh](https://skills.sh):

```bash theme={null}
npx skills add https://github.com/lxcong/web3-data-skill --skill web3-data
```

Or install via [ClawHub](https://clawhub.ai):

```bash theme={null}
npm i -g clawhub
clawhub install lxcong/web3-data
```

You can also clone the repository and install manually:

```bash theme={null}
git clone https://github.com/lxcong/web3-data-skill.git
cd web3-data-skill
claude skill install ./skills.sh
```

## Configuration

Set your Chainbase API key as an environment variable (required for on-chain data):

```bash theme={null}
export CHAINBASE_API_KEY="your_api_key_here"
```

You can obtain an API key from the [Chainbase Console](https://console.chainbase.com/).

<Note>
  The Tops social intelligence commands do not require an API key and are free to use.

> /web3-data show NFTs owned by vitalik.eth
> /web3-data label the address 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045
