kale.x420.dev is a single-endpoint DeFi trading API on the Base network that enables programmatic purchases of KALE tokens by spending a custom USDC amount. The /api/puff-custom endpoint lets applications execute one-click or automated buys of KALE for a specified USDC value. Pricing is fixed (listed at $5 per call), making it straightforward to integrate into trading bots, wallets, or UIs that need deterministic on‑chain token purchases.
