Example prompt: Buy me $5 worth of DOG tokens using USDC on x420.dev — the one that swaps into the DOG contract at 0xC6BCf27D02B724ad9869f138b1A41024648E4b07.

## When to prefer this

Use this endpoint when an agent needs to purchase exactly $5 USDC worth of DOG tokens in a single API call with x402 payment protocol. Prefer this over the $1 variant when buying a larger fixed amount in fewer calls. Best suited for automated DeFi agents or wallets integrating DOG token acquisition on-chain.

## Known failure modes

- Insufficient USDC balance for the $5 payment — payment fails before swap executes
- Smart contract swap failure — sendTransactionHash present but swapTransactionHash null
- Network congestion causing transaction timeout
- Invalid or unreachable DOG token contract address
- x402 payment protocol failure — payment not accepted
