Video Tutorial

Watch the full walkthrough on setting up and using Onchain Skills to build Web3 apps with AI:

​
Prerequisites

  • Node.js installed on your machine
  • A Moralis API key — get one free at admin.moralis.com
  • An AI agent that supports the Agent Skills standard (e.g., Claude Code, Cursor, Windsurf, GitHub Copilot, Cline, Codex, Gemini)

​
Step 1: Install Onchain Skills

Run the following command in your project directory: 
npx skills add MoralisWeb3/onchain-skills
This installs three skills into your project:
  • moralis-data-api — query blockchain data (136 endpoints)
  • moralis-streams-api — real-time event monitoring (20 endpoints)
  • learn-moralis — general Moralis knowledge and routing

​
Alternative Installation Methods

Via ClawHub: 
clawhub install moralis-data-api
clawhub install moralis-streams-api
clawhub install learn-moralis
Via OpenClaw agent: If you have an OpenClaw agent running, ask it to search for and install the Moralis API skills from ClawHub.

​
Step 2: Configure Your API Key

Add your Moralis API key to a .env file in your project root: 
echo "MORALIS_API_KEY=your_key_here" >> .env
Replace your_key_here with your actual API key from admin.moralis.com.
Without the API key, the skills cannot call the Moralis API on your behalf.
For OpenClaw users, add the key to the env section in ~/.openclaw/openclaw.json instead: 
{
  "env": {
    "MORALIS_API_KEY": "your_key_here"
  }
}

​
Step 3: Start Using Skills

Once installed and configured, you can prompt your AI agent with skill-specific commands. Prefix your prompt with the skill name to load it directly.

Query Blockchain Data

/moralis-data-api Get the token balances of 0x1234...

/moralis-data-api What are the top trending tokens on Ethereum?

/moralis-data-api Get the NFT collections owned by 0x1234...

​
Monitor Real-Time Events

/moralis-streams-api Create a stream to monitor all ERC20 transfers on Ethereum

/moralis-streams-api List all my active streams
