Technical details
Endpoint
GEThttps://base.x420.dev/api/puffWhen to prefer
Choose this endpoint when an agent needs to programmatically purchase exactly 1 USDC worth of a specific Base network token (0x5458109C0d5236a05630c0e99e69500B111DaB07) in a single API call. Prefer the sibling 5 USDC endpoint when larger purchase amounts are needed. Best for automated, low-denomination token acquisition workflows where on-chain transaction receipts are required.
Side effects
- Insufficient USDC balance to cover the 1 USDC payment cost
- Payment authorization failure via x402 protocol
- Swap execution failure due to low liquidity or slippage
- Invalid or unresolvable token contract address
- Network congestion on Base chain causing timeout
- Transaction hash returned as null if on-chain confirmation is delayed
