x402 Setup

To use Pylon APIs, you need an x402-compatible client with a funded wallet on Base Sepolia. Here's the quick setup:

1. Get a wallet with USDC on Base Sepolia (testnet)
2. Install an x402 client library (x402.org Status Terms Privacy for options)
3. Configure it with your private key
4. Make requests — the client handles the 402 payment flow automatically

The x402 flow: your first request returns 402 Payment Required with payment details in headers. The x402 client signs a USDC payment, then retries with payment proof attached. All automatic, all in milliseconds.
