Agenthub

AgentHub — 32 AI APIs, pay per call in USDC

You have access to AgentHub, a gateway that lets you call real-world data APIs. Payment is handled automatically via the x402 protocol — gasless USDC on Base Mainnet.

Gateway URL: https://agents-production-73c1.up.railway.app

Setup (one time)

1. Install the SDK

npm install --prefix ~/.openclaw/workspace/skills/rwagenthub rwagenthub-sdk

This installs the SDK inside the skill's own folder — no global install, no permission issues, works on any system.

SDK package: npmjs.com/package/rwagenthub-sdk

2. Configure your wallet private key

⚠️ Use a dedicated wallet with only the USDC you need. Never use your main wallet.

openclaw config set env.MCP_WALLET_PRIVATE_KEY "0xYOUR_PRIVATE_KEY_HERE"

Security note: The private key never leaves your device. The SDK uses it to sign an EIP-3009 gasless authorization locally — only the signed authorization (not the key) is sent to the payment network. The key is used solely to sign USDC micropayments on Base Mainnet.

3. Add USDC to your wallet on Base Mainnet

• Min recommended: $1 USDC (covers 100+ calls at $0.01 each)
• Buy USDC and withdraw to Base network via Coinbase or any exchange

Before every call — verify SDK is installed

Run this check before making any API call. If the SDK is missing, install it automatically:

[ -f "$HOME/.openclaw/workspace/skills/rwagenthub/node_modules/rwagenthub-sdk/index.js" ] || \
  npm install --prefix "$HOME/.openclaw/workspace/skills/rwagenthub" rwagenthub-sdk --silent

If MCP_WALLET_PRIVATE_KEY is not set, tell the user:

"Please run: openclaw config set env.MCP_WALLET_PRIVATE_KEY \"0xYOUR_PRIVATE_KEY\""

How to call an API

For every API call, create a temporary script and run it with node:

cat > /tmp/agenthub-call.mjs << SCRIPT
import AgentHub from '$HOME/.openclaw/workspace/skills/rwagenthub/node_modules/rwagenthub-sdk/index.js';

const hub = new AgentHub({ privateKey: process.env.MCP_WALLET_PRIVATE_KEY });
const result = await hub.call('API_NAME', { ...inputs... });
console.log(JSON.stringify(result, null, 2));
SCRIPT

node /tmp/agenthub-call.mjs

Replace API_NAME and { ...inputs... } with the API and parameters from the list below.
