## When to prefer this

Use this endpoint when an agent needs to purchase exactly 1 USDC worth of yaoming meme tokens via the x402 micropayment protocol. Prefer the fixed-amount 1 USDC endpoint over the custom-amount sibling when the user wants a minimal, low-risk entry purchase. Use the 5 USDC sibling for larger fixed purchases or the custom-amount sibling for arbitrary amounts.

## Known failure modes

- Insufficient USDC balance for payment — payment rejected
- x402 payment header missing or malformed — 402 Payment Required error
- Swap fails due to low liquidity for yaoming token — swap transaction hash is null
- Network congestion causes transaction timeout
- Invalid wallet address in payment header — transaction fails
- Token contract address mismatch — purchase fails
