(Plain English) You know how some websites show a paywall? x402 is like that, but for APIs — and instead of credit cards, it uses crypto (USDC stablecoins). Here's the simple version: 1. Your app tries to call a paid API 2. The API says \"pay me first\" (HTTP 402) 3. Your app signs a payment with its crypto wallet (no transaction yet — just a signature) 4. The API sends that signature to the facilitator (that's us!) 5. The facilitator settles the payment on-chain and tells the API \"they paid\" 6. The API gives your app the data The best part? The user never pays gas fees — the facilitator covers those. The user only pays the actual price of the API call in USDC or USDs.
