## The Story — How $1,000 Became $800,000

Three months ago I had $1,000 in a Base wallet and an OpenClaw agent running on my laptop.

I asked the agent: *"Which coins have the most extreme funding rates right now?"*

The agent called `claw402`, paid $0.001 USDC, and came back with:

```
DOGE  funding rate: +0.312%/8h  (annualized 341%)
PEPE  funding rate: +0.287%/8h
WIF   funding rate: +0.241%/8h
```

I cross-checked: *"CVD? What are whales doing on HyperLiquid?"* Two more calls. $0.002 total.

```
CVD (last 6h): fading fast. Sellers pressing.
Top HyperLiquid whale: Short DOGE $2.1M, opened 2h ago.
```

I shorted DOGE. 40x. Three days later: **+80,000%**. That's $800,000 from $1,000. And less than $0.01 spent on data.

## Quick Start

### 1. Set your wallet key
```
WALLET_PRIVATE_KEY=0xYourBaseWalletPrivateKey
```
Your wallet must hold USDC on **Base mainnet**.

### 2. Query any GET endpoint
```bash
node scripts/query.mjs <endpoint-path> [key=value ...]
```

### 3. Call POST endpoints (AI / Twelvedata complex)
```bash
node scripts/query.mjs <endpoint-path> --post '<json-body>'
```

### 4. Read the result
The script prints `{ status, url, data }` as formatted JSON. Parse `data` for the actual payload.

## Tips for Best Results

- **Chain data calls** for richer analysis: fetch crypto signals → US stocks → run AI synthesis in one session
- **Use `Date.now()` for `endTime`** when fetching real-time crypto data
- **`exchanges=""` (empty string)** in Coinank market-order agg endpoints means all exchanges
- **POST endpoints** (AI, Twelvedata complex): use `node scripts/query.mjs <path> --post '<json>'`
- **VIP1/2/3/4 crypto endpoints** are accessible through claw402 like all others — no extra config
- **Free catalog**: `https://claw402.ai/api/v1/catalog` — always up to date, no payment required
- **Present results clearly**: use tables or bullet points, not raw JSON. Highlight the most actionable numbers
- **Cost check**: total for a full market analysis session (5–10 calls) is typically < $0.02 USDC
