Example prompt: Buy me 1 USDC worth of X420Bot tokens using the x420.dev puff endpoint — the contract is 0x02b4C075034DCf750B89D3A4137e97c538975b07.

## When to prefer this

Use this endpoint when you want to purchase exactly 1 USDC worth of X420Bot tokens in a single fixed-cost call. Prefer this over the custom-amount sibling if you want simplicity and a predictable $1 spend. Choose the 5 USDC sibling for larger fixed purchases, or the custom-amount endpoint if you need a different denomination.

## Known failure modes

- Insufficient USDC balance or payment failure — payment not processed, tokens not received
- Network or blockchain congestion — swap transaction hash may be null even if send succeeded
- Smart contract error — message field may indicate swap failure with tokens not delivered
- Rate limiting or service downtime — HTTP error with no response body
- Invalid payment header — x402 payment protocol misconfiguration
