Endpoint
POSThttps://api.loyalspark.online/x402-gateway/recipient-mcp-tools/list_my_loyalty_balancesWhen to prefer
Use this endpoint when an AI agent or user needs to audit their current loyalty token holdings across all Loyal Spark programs on Base L2. Prefer this over general blockchain balance queries when the context is specifically about loyalty rewards earned through Loyal Spark merchants or campaigns, and when the goal is to decide what to redeem or trade P2P.
