Run a live decode through the full x402 flow
The interactive playground runs the full x402 pay-per-call flow on Base Sepolia testnet with a server-funded demo key.
Demo runs on testnet. This site is live on Base mainnet, where each call is paid from your own wallet rather than a shared demo key. Follow the production pay-per-call flow — request, 402 quote, signed USDC payment, retry — in the decode endpoint reference, with runnable curl, JavaScript and Python examples. See pricing for the per-call cost.
