Technical details
Endpoint
GEThttps://flash.x420.dev/api/puff?utm_source=zero.xyzWhen to prefer
Use this endpoint when you want to purchase a fixed $1 USDC amount of FLASH tokens in a single atomic API call without specifying a custom amount. Prefer this over the custom-amount sibling endpoint when simplicity and a standard fixed denomination are sufficient. Choose this over manual DEX interaction when you need programmatic, agent-driven token acquisition.
Side effects
- Insufficient USDC balance to cover the $1 cost — payment rejected
- Smart contract or swap failure resulting in null transaction hashes
- Network congestion causing delayed or failed on-chain settlement
- Invalid or expired x402 payment authorization — 402 error returned
- FLASH token contract unavailable or paused — swap cannot complete
