This provider exposes a single DeFi trading endpoint on the Base network that performs a micro-swap: calling /puff triggers a buy of 1 USDC worth of x420 tokens (via x420.dev). The API is optimized for simple, repeatable on-chain token purchases and is presented as a zero-cost service (note: on-chain gas costs still apply). It is well suited for testing, onboarding, faucets, and lightweight automation around the x420 token.
