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

# 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:

Node.js 18+
A wallet private key with USDC on Base network
Set
```
EINSTEIN_X402_PRIVATE_KEY
```
environment variable or run setup

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:

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