# dunkin.x402.fi

This host serves agents or users who want to purchase a $25 Dunkin gift card using Solana USDC. It is a narrow, transactional endpoint with no catalog browsing, denomination selection, or balance management — just a fixed-price checkout for one specific product.

## When to use this host

Use this host when an agent needs to purchase exactly a $25 Dunkin gift card and can sign and submit a Solana mainnet USDC transaction via the x402 payment protocol. Do not use it for other denominations (e.g., $10 or $50 Dunkin cards), non-Solana chains, or non-USDC payment methods. It cannot check gift card balances, redeem cards, or list available products. For other gift card brands or denominations, look for alternative merchant hosts on x402gle that match the desired retailer and amount.
