description: doordash.x402.fi is a single-purpose payment endpoint that processes a fixed $50 USDC purchase on Solana mainnet to acquire a DoorDash $50 gift card or store credit. It implements the x402 paywall protocol with an exact-amount scheme and a 5-minute settlement window. No other denominations, networks, or merchants are supported.

# doordash.x402.fi

This host serves agents that need to programmatically buy a DoorDash $50 gift card using USDC on Solana mainnet via the x402 protocol. It is narrowly scoped: one merchant, one denomination, one network. It is not a general gift card marketplace or a multi-chain payment router — it is a direct checkout endpoint for this specific product.

## When to use this host

Use this host when an agent needs to purchase exactly a $50 DoorDash gift card or store credit and can pay 50 USDC on Solana mainnet. Do not use it for any other amount (e.g., $25 or $100 DoorDash cards), for other food delivery platforms (Uber Eats, Grubhub), for non-Solana networks (Ethereum, Base, etc.), or for variable-amount or partial payments. If the agent needs a general gift card purchasing service across multiple merchants or denominations, a broader gift card API host should be used instead. Callers must supply a valid Solana fee payer address and a recognized apiId in the extra fields.
