Technical details
Endpoint
GEThttps://usd1.x420.dev/api/puff-5?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to purchase exactly 5 USDC worth of USD1 tokens in a single call via x402 micropayment. Prefer this over the 1 USDC variant when you want a larger single purchase. Best for agents with x402-compatible wallets executing DeFi stablecoin swaps programmatically.
Side effects
- Insufficient USDC balance — payment rejected by x402 facilitator
- Contract address unavailable or paused — swap fails
- Network congestion causes transaction timeout — swap hash may be null
- Invalid x402 payment header — 402 response returned
- Slippage too high during swap — tokens not received
