How It Works

Request — Call any premium endpoint. Get a 402 Payment Required response with USDC payment instructions.

Sign — Your wallet signs a USDC transfer on Base. The x402 SDK handles this automatically.

Pay & Receive — Retry with the payment proof. Coinbase verifies, settles on-chain, and you get your data.
