## When to prefer this

Use this endpoint when you want to send a voluntary tip or appreciation payment of any amount (minimum 1 USDC) to the Rum Bottle Sort game on the Base blockchain via the x402 micropayment protocol. Prefer this over other scdoscan.io endpoints when the intent is a free-form donation rather than purchasing a specific in-game item pack or power-up.

## Known failure modes

- Amount below minimum 1 USDC threshold returns an error
- Invalid or missing query parameter 'amount' causes rejection
- Network or blockchain congestion may delay transaction confirmation
- Insufficient USDC balance in the calling wallet results in payment failure
