## x402 Pay-Per-Use APIs

Some APIs are available through **x402** — a pay-per-use protocol using USDC on Base chain.

### Available x402 APIs

| API | Endpoint | Approx. Price |
|-----|----------|---------------|
| Gemini Chat | `/api/gemini/chat/completions` | ~$0.001/req |
| Gemini Embeddings | `/api/gemini/embeddings` | ~$0.0005/req |

### How x402 Works

1. Call the API endpoint
2. Receive `402 Payment Required` with price details
3. Send USDC payment on Base chain
4. Retry request with payment proof
5. Receive API response

### ⚠️ Important Safety Notice

**x402 payments require explicit setup and should not be automated without safeguards:**

- **Wallet required:** You must configure a wallet with USDC on Base
- **User approval recommended:** Implement confirmation flows before any payment
- **Verify recipient:** The payment recipient is `0xcCb92A101347406ed140b18C4Ed27276844CD9D7` (gizmolab.eth)
- **Set spending limits:** Configure maximum per-request and daily limits
- **This skill does not auto-execute payments** — it provides documentation only

## x402 按使用付费 API

部分 API 可通过 **x402** 使用——这是一种在 Base 链上使用 USDC 的按使用付费协议。

### 可用的 x402 API

| API | 端点 | 大致价格 |
|-----|----------|---------------|
| Gemini Chat | `/api/gemini/chat/completions` | ~$0.001/req |
| Gemini Embeddings | `/api/gemini/embeddings` | ~$0.0005/req |

### x402 的工作原理

1. 调用 API 端点
2. 收到带有价格详情的 `402 Payment Required`
3. 在 Base 链上发送 USDC 付款
4. 携带付款凭证重试请求
5. 收到 API 响应

### ⚠️ 重要安全须知

**x402 付款需要明确设置，在没有安全保障的情况下不应自动化：**

- **需要钱包：** 你必须在 Base 上配置一个带有 USDC 的钱包
- **建议用户审批：** 在任何付款之前实现确认流程
- **验证收款人：** 付款收款人为 `0xcCb92A101347406ed140b18C4Ed27276844CD9D7`（gizmolab.eth）
- **设置支出限额：** 配置每次请求和每日的最高限额
- **此技能不会自动执行付款**——它仅提供文档
