Use this endpoint when you want to purchase exactly $5 USDC worth of TEST9999 tokens in a single fixed-amount call. Prefer this over the $1 tier when buying a larger fixed amount, or over the custom-amount endpoint when you specifically want a standard $5 purchase with no additional input needed.

- Network congestion causing transaction delay or failure
- x402 payment header missing or malformed — 402 Payment Required response
- Token contract address mismatch or contract not found on chain
