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.

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.
