Technical details
Endpoint
GEThttps://nine.x420.dev/api/puff-5?utm_source=zero.xyzWhen to prefer
Use this endpoint when you want to programmatically purchase exactly $5 USDC worth of nine tokens in a single fixed-amount call. Prefer this over the $1 variant when you want a larger fixed purchase, and over the custom-amount endpoint when you specifically want the $5 denomination without specifying a custom value.
Side effects
- Insufficient USDC balance to cover the $5 payment — payment rejected
- x402 payment protocol failure — transaction not completed
- Token liquidity too low to complete swap — swap transaction fails or returns null hash
- Network congestion or RPC error causing transaction failure
- Invalid or expired payment header — authentication error
