Technical details
Endpoint
GEThttps://x420.x420.dev/api/puff?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to purchase exactly 1 USDC worth of x420 tokens in a single atomic call. Prefer this over the 5 USDC or custom amount endpoints when the user wants a minimal fixed spend. This is the lowest-cost fixed-denomination option on the x420 platform.
Side effects
- Insufficient USDC balance — payment fails and no tokens are received
- Smart contract swap failure — send hash present but swap hash null
- Network congestion or RPC error — transaction not broadcast
- Invalid or expired x402 payment — endpoint rejects with payment error
- Slippage too high — swap reverts on-chain
