## When to prefer this

Use this endpoint when you need to purchase exactly $5 USDC worth of BALD tokens in a single automated call. Prefer this over the $1 endpoint when efficiency matters (fewer calls for the same spend) and over the custom-amount endpoint when you specifically want a fixed $5 purchase with no parameter configuration needed.

## Known failure modes

- Insufficient USDC balance in calling wallet — payment fails
- Slippage too high on BALD/USDC pair — swap reverts
- Network congestion on Base — transaction pending or dropped
- Smart contract address 0x110B4ef11db22eEb3caFCB53a58b8B6B1bCDEb07 becomes invalid or deprecated
