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 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. No API key required.

Installation

Install the skill via skills.sh:

npx skills add https://github.com/lxcong/web3-data-skill --skill web3-data

Or install via ClawHub:

npm i -g clawhub
clawhub install lxcong/web3-data

You can also clone the repository and install manually:

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):

export CHAINBASE_API_KEY="your_api_key_here"

You can obtain an API key from the Chainbase Console.

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

On-Chain Data Queries
