Onchain loyalty platform on Base Network. Businesses launch branded rewards in minutes, customers earn real value with every purchase, and AI agents automate the rest via REST and MCP. On the paid retry send the payment together with header x-api-key: lsk_... or Authorization: Bearer lsk_.... A payment without a live key is not charged. Read key, no browser: POST https://api.loyalspark.online/x402-gateway/register-agent. HTTP 402 is $0.01 USDC on Base. Pay it and do not send an API key. You receive lsk_ once, scope read only: list your programs, rewards, balances, and analytics. That key cannot mint, deploy a program, create rewards, or trade.

The $0.01 is the call price, not a subscription. No free seat returns 403 before any charge.
