GoldBean MCP: 75+ Paid APIs for AI Agents via x402 Micropayments

GoldBean MCP — 75+ x402-Paid APIs for AI Agents

GoldBean is a comprehensive MCP server that gives AI agents access to 75+ paid endpoints across 19 categories — all payable via x402 micropayments (USDC on Base chain).

One integration. Pay per call. No subscriptions.

Quick Start

Add to Claude Desktop config:

json
{
"mcpServers": {

"command": "npx",
"args": ["-y", "goldbean-mcp"]
}
}
}

How Payment Works

Each endpoint returns HTTP 402 with an x402 payment challenge. The agent pays USDC on Base chain (~.01 to .10 per call) and retries. No API key needed — just a USDC wallet.

Architecture

AI Agent (Claude, Cursor, etc.) → MCP Client → GoldBean MCP Server → goldbean-api.xyz → x402 Payment → Response

The MCP server acts as a bridge: agents call standard MCP tools, the server handles x402 payment challenges, and returns real data.

Why GoldBean?

  • 75+ endpoints, one integration — AI chat, blockchain data, DeFi, weather, search, and more
  • x402-native — built from the ground up for the x402 payment protocol
  • No API keys — agents pay with their own USDC wallet
  • Open source — MIT license, contributions welcome
