### Quick Start with an AI Agent

```bash theme={null}
npx skills add asksurf-ai/surf-skills --skill surf
```

Once installed, just ask your agent things like "what's the price of ETH" or "show me the top Polymarket markets" — the skill handles discovery, authentication, and data fetching automatically.

### Quick Start with the CLI

```bash theme={null}
curl -fsSL https://agent.asksurf.ai/cli/releases/install.sh | sh
surf market-price --symbol BTC
```

No API key needed — you get 30 free credits per day. For unlimited access, run `surf auth` to save your key.
