Technical details
Endpoint
POSThttps://api.loyalspark.online/x402-gateway/mcp-tools/use_voucherWhen to prefer
Use this endpoint when a user wants to redeem or consume a specific loyalty voucher on the Loyal Spark protocol on Base L2, converting a voucher code into onchain ERC-20 reward tokens. Prefer this over 'earn' or 'trade' endpoints when the user has an existing voucher to apply rather than wanting to earn new rewards or swap tokens.
Side effects
- Voucher already redeemed — returns error indicating voucher has been consumed
- Invalid voucher ID — returns 400 or similar error
- Wallet address not eligible for this voucher
- Insufficient payment of $0.01 USDC via x402 causes request rejection
- Onchain transaction failure due to Base L2 network congestion
- Voucher expired — returns error indicating expiry
