Einstein x402 区块链分析

说明文档

# Einstein — Blockchain Analytics via x402

Einstein provides 27 blockchain analytics services accessible via x402 micropayments (USDC on Base). Each query costs $0.25–$1.15 depending on complexity.

## Quick Start

```bash
# 1. Install dependencies (manual step — the setup wizard will NOT run npm for you)
cd packages/project-einstein/openclaw-skill/einstein && npm install

# 2. Set your private key via environment variable (recommended)
export EINSTEIN_X402_PRIVATE_KEY=0x_your_private_key_here

# 3. Or run the interactive setup wizard
node scripts/einstein-setup.mjs

# 4. List all services (free)
node scripts/einstein.mjs services

# 5. Run a query (will prompt for payment confirmation)
node scripts/einstein.mjs top-movers --chain base --limit 10
```

**Requirements:**
- Node.js 18+
- Dependencies installed via `npm install` (not auto-installed)
- A **dedicated** wallet private key with USDC on Base network (do NOT use your main wallet)
- Set `EINSTEIN_X402_PRIVATE_KEY` environment variable (preferred) or run setup with `--save-config`

## How Payment Works

Einstein uses the **x402 protocol** — an HTTP-native micropayment standard. Payment is automatic:

1. Your request hits Einstein's endpoint
2. Server responds with HTTP 402 + payment challenge
3. The skill signs a USDC TransferWithAuthorization (EIP-3009) using your private key
4. Request is re-sent with the payment signature
5. Coinbase CDP facilitator settles the USDC transfer on Base
6. You receive the analytics data

**No accounts, no API keys, no subscriptions.** Just USDC on Base and a private key.

## Options Reference

### `einstein.mjs` (query CLI)

| Flag | Description | Default |
|------|-------------|---------|
| `--chain <chain>` | Blockchain network | `base` |
| `--limit <N>` | Number of results (1-500) | `10` |
| `--timeperiod <period>` | Time window: 1d, 3d, 7d, 30d | `7d` |
| `--token <address>` | Token contract address | — |
| `--wallet <address>` | Wallet address | — |
| `--chains <c1,c2>` | Comma-separated chains | — |
| `--raw` | Data-only response (cheaper) | `false` |
| `--yes` / `-y` | Skip payment confirmation prompt | `false` |

To skip the confirmation prompt globally, set `EINSTEIN_AUTO_CONFIRM=true` or add `"autoConfirm": true` to config.json.

### `einstein-setup.mjs` (setup wizard)

| Flag | Description | Default |
|------|-------------|---------|
| `--key <privateKey>` | Private key (skips interactive prompt) | — |
| `--url <baseUrl>` | Base URL for Einstein API | `https://emc2ai.io` |
| `--chain <chain>` | Default blockchain network | `base` |
| `--save-config` | Write config.json to disk (otherwise prints env var exports) | `false` |

**Supported chains:** base, ethereum, bsc, solana, arbitrum, polygon, optimism, zksync

## Security Best Practices

**Use a dedicated wallet.** Create a separate wallet funded with a small amount of USDC for this skill. Do NOT use your primary wallet or any wallet holding significant funds.

**Prefer environment variables over config.json.** Environment variables (`EINSTEIN_X402_PRIVATE_KEY`) are not persisted to disk and are harder to accidentally commit to git. If you must use config.json (`--save-config`), restrict file permissions:

```bash
chmod 600 config.json
```

**What gets signed.** Each paid query signs an EIP-3009 `TransferWithAuthorization` message that authorizes a USDC transfer of the exact query price (shown before confirmation) from your wallet to the Einstein service address. The signature is single-use (unique nonce) and time-limited. No blanket approvals are granted.

**Payment confirmation.** By default, the CLI prompts before every paid query showing the exact cost. To skip the prompt for scripted/automated use, pass `--yes` / `-y` per-command or set `EINSTEIN_AUTO_CONFIRM=true` globally.

**No auto-installed packages.** The setup wizard does NOT run `npm install` automatically. You must install dependencies yourself so you can audit what is being installed.

**No home directory scanning.** Configuration is loaded only from environment variables and the skill-local `config.json`. No paths outside the skill directory are read.

## Troubleshooting

**"No private key configured"**
Set `EINSTEIN_X402_PRIVATE_KEY` environment variable or run `node scripts/einstein-setup.mjs --save-config`.

**"Payment rejected" / "Insufficient balance"**
Your wallet needs USDC on Base. Bridge via https://bridge.base.org. Use a dedicated wallet with a small balance.

**"Cannot reach emc2ai.io"**
Check internet connection. The service may have temporary downtime.

**"Unknown service"**
Run `node scripts/einstein.mjs services` to see all available commands.

**"Dependencies not installed"**
Run `npm install` in the skill directory: `cd packages/project-einstein/openclaw-skill/einstein && npm install`
