Arkham Intelligence API Skill for Claude Code

Unofficial community project - This is not affiliated with, endorsed by, or officially supported by Arkham Intelligence or Anthropic.

A Claude Code skill that integrates the Arkham Intelligence API for blockchain analytics directly into your AI coding assistant. Track whales, analyze wallets, monitor smart money & investigate token flows using natural language.

What is this?

This repository provides a Claude Code skill that enables Claude to interact with the Arkham Intelligence API. With this skill, you can ask Claude to:

Analyze wallet addresses and their holdings
Track whale movements and large transfers
Investigate token holders and smart money positions
Monitor trending tokens and market flows
Research entities like exchanges, market makers, and funds
Get real-time blockchain intelligence across 10+ chains

Prerequisites

Claude Code CLI installed and configured
An Arkham Intelligence API key
curl and jq installed on your system

Getting Your Arkham API Key

Go to Arkham Intelligence Platform
Create an account or sign in
Navigate to Settings > API Keys
Click Generate API Key
Copy your API key (you won't be able to see it again!)

Note: Arkham API has different tiers with varying rate limits. Check their API documentation for details.

Installation

Option 1: Clone to your project (Recommended)

Clone this repository into your project's .claude/skills/ directory:

# Navigate to your project
cd your-project
Create the skills directory if it doesn't exist
mkdir -p .claude/skills
Clone this repo as a skill
git clone https://github.com/Vyntral/arkham-intelligence-claude-skill .claude/skills/arkham-api

Option 2: Install globally for all projects

Clone to your personal Claude Code skills directory:

# Create global skills directory
mkdir -p ~/.claude/skills
Clone this repo
git clone https://github.com/Vyntral/arkham-intelligence-claude-skill ~/.claude/skills/arkham-api

Option 3: Manual installation

Download or copy the .claude/skills/arkham-api/SKILL.md file
Place it in your project's .claude/skills/arkham-api/ directory
Optionally copy ARKHAMAPIDOCUMENTATION.md to the same location for detailed API reference

Configuration

Step 1: Set up your API key

Copy the example settings file and add your API key:

# For project-specific configuration
cp .claude/settings.local.json.example .claude/settings.local.json
Edit and add your key
nano .claude/settings.local.json

Or add to your global Claude Code settings (~/.claude/settings.json):

{
  "env": {
    "ARKHAMAPIKEY": "your-api-key-here"
  }
}

Step 2: Configure permissions (optional)

The skill requires permissions to make curl requests. Add to your settings:

{
  "permissions": {
    "allow": [
      "Bash(curl:*)",
      "Skill(arkham-api)"
    ]
  }
}

Step 3: Restart Claude Code

After adding your API key, restart Claude Code for changes to take effect.

Security Notes

Never commit your API key - The .gitignore is configured to exclude .claude/settings.local.json
Store API keys in user-level settings (~/.claude/settings.json) for personal keys
Use project-level settings (.claude/settings.local.json) for project-specific keys
The skill only has access to curl and read-only file operations
