# 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](https://www.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

```bash
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.

```bash
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](https://coinbase.com) 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:

```bash
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:

```bash
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.
