You can use this server directly with npx or install it globally.

Prerequisites

To use this paid API, you need:

1. An Ethereum wallet (EVM) formatted private key.
2. USDC on Base Mainnet in that wallet to pay for requests ($0.03/req).

Quick Start (Claude Desktop)

Add this to your claude_desktop_config.json:
