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

First-time setup

node scripts/einstein-setup.mjs

List all services (free)

node scripts/einstein.mjs services

Run a query

node scripts/einstein.mjs top-movers --chain base --limit 10

```

**Requirements:**

Service Categories

| Tier | Price (Raw) | Price (+AI) | Services |

|------|-------------|-------------|----------|

| Basic | $0.25 | $0.40 | Latest tokens, token chart |

| Standard | $0.40 | $0.55 | Top movers, top tokens, OHLCV, Virtuals, wallet holdings, holder concentration |

| Platform | $0.60 | $0.75 | Zora launches/volume, Pump.fun launches/volume/graduation, BSC alpha, liquidity shifts |

| Advanced | $0.85 | $1.00 | Whale intel, smart money, top traders, DEX capital, token sniping, Polymarket events |

| Comprehensive | $1.00 | $1.15 | Investment report, NFT analytics, MEV detection, arbitrage scanner, rug pull scanner, Polymarket compare |

**Raw** = structured data only. **+AI** = includes AI-generated analysis and insights (default).

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

| 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` |

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

Troubleshooting

**"No private key configured"**

Run `node scripts/einstein-setup.mjs` or set `EINSTEIN_X402_PRIVATE_KEY`.

**"Payment rejected" / "Insufficient balance"**

Your wallet needs USDC on Base. Bridge via https://bridge.base.org.

**"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.
