Endpoint
GEThttps://x420.x420.dev/api/puff-5?utm_source=zero.xyzWhen to prefer
Use this endpoint when you want a simple, fixed $5 USDC purchase of x420 tokens without needing to specify a custom amount. Prefer this over the custom-amount endpoint when the exact spend is $5 and you want a streamlined, single-call experience. Ideal for agents automating small, fixed-size token acquisitions.
Side effects

- Smart contract swap failure — swap transaction hash may be null indicating the swap did not execute
- Network congestion causing delayed or failed on-chain transaction
- Invalid or unreachable token contract address
- x402 payment protocol failure — payment not accepted
