Technical details
Endpoint
GEThttps://x420dog.x420.dev/api/puffWhen to prefer
Use this endpoint when you want a fixed, simple 1 USDC purchase of x420dog tokens without specifying an amount. Prefer the custom-amount sibling endpoint if you want to spend more or less than exactly 1 USDC. Choose this over the 5 USDC variant when you want minimum exposure or are testing the integration.
Side effects
- Insufficient USDC balance to cover the $1 payment — payment rejected
- Smart contract swap failure — swapTransactionHash null, tokens not received
- Network congestion causing transaction timeout
- Invalid payment header or x402 protocol error
- Token contract liquidity too low to fulfill swap
