AgentHub — 32 AI APIs, pay per call in USDC
You have access to AgentHub, a paid API gateway for real-world data.
- What it does: Routes API calls to 32 data providers (flights, weather, stocks, etc.)
- How payment works: Each call costs $0.01–$0.06 USDC, charged automatically via the x402 micropayment protocol on Base Mainnet. The wallet credential signs a gasless USDC transfer locally — no gas fees, no custody of funds by the gateway.
- SDK source: npmjs.com/package/rwagenthub-sdk — open source, auditable, no obfuscation. Only calls
https://agents-production-73c1.up.railway.app/v1/call and the Base Mainnet RPC.
- 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@1.0.2
Installs the pinned SDK version into the skill's own folder. No global install required.
2. Configure your wallet credential
⚠️ Use a dedicated wallet funded only with the USDC you need for API calls. Do not use a primary wallet.
openclaw config set env.AGENTHUB_WALLET_KEY "YOUR_WALLET_CREDENTIAL"
The credential is used locally to sign a USDC micropayment authorization. Only the signed authorization (not the credential itself) is sent over the network. The gateway never receives or stores the credential.
3. Add USDC to your wallet on Base Mainnet
- Minimum recommended: $1 USDC (covers 100+ calls at $0.01 each)
- Acquire USDC via Coinbase or any exchange, withdraw to Base network
Before every call — verify SDK is installed
Run this check before making any API call. Installs automatically if missing:
SDK_DIR="$HOME/.openclaw/workspace/skills/rwagenthub"
[ -f "$SDK_DIR/node_modules/rwagenthub-sdk/index.js" ] || \
npm install --prefix "$SDK_DIR" rwagenthub-sdk@1.0.2 --silent
If AGENTHUB_WALLET_KEY is not set, tell the user:
"Please run: openclaw config set env.AGENTHUB_WALLET_KEY \"YOUR_WALLET_CREDENTIAL\""
How to call an API
For every API call, write a temporary script and run it with Node.js:
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.AGENTHUB_WALLET_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 name and parameters from the list below.
