Documentation Overview

🫘 GoldBean - x402 Micropaid API Marketplace

Pay per request with USDC on Base. No signup, no API key, no monthly subscription. Every call costs $0.02 USDC via the x402 protocol.

GoldBean is live: http://104.225.233.23:9879

Quick Start

1. Prerequisites

USDC on Base (eip155:84532 testnet or eip155:8453 mainnet)
A wallet that can sign x402 payments (AgentCash, CDP Wallet, or any EVM wallet)

2. Try a Free Endpoint

Terminal

curl http://104.225.233.23:9879/health
# {"status":"ok","service":"GoldBean","timestamp":"2026-05-15T12:00:00.000Z"}

curl http://104.225.233.23:9879/eth-price
# {"usd":"2255.93","change24h":"+0.31%","timestamp":"2026-05-15T12:00:00.000Z"}

3. Call a Paid Endpoint

Terminal

curl http://104.225.233.23:9879/paid/btc-price
# HTTP 402 Payment Required
# x402-challenge: {...}

To pay the 402 and get data, you need an x402-capable client:

Using AgentCash:

Terminal

npx agentcash@latest fetch http://104.225.233.23:9879/paid/btc-price

Using x402-proxy (CLI tool):

Terminal

npx x402-proxy http://104.225.233.23:9879/paid/btc-price

Using curl with manual payment (advanced):

bash

# Step 1: Request triggers 402
curl -s -D - http://104.225.233.23:9879/paid/btc-price

# Step 2: Parse x402-challenge header, sign with your wallet
# Step 3: Retry with x402-payment header
curl -H "x402-payment: <signed-payment>" http://104.225.233.23:9879/paid/btc-price

4. MCP Integration

Add to Claude Desktop / Cursor / Cline mcpServers config:

config.json

{
  "mcpServers": {
    "goldbean": {
      "url": "http://104.225.233.23:9879/mcp"
