Playground
Connect with Web3Auth, mint free DEMO-USDT, then either pay yourself across the eight endpoints below or hand the work to a delegated agent. Gas sponsored by paymaster.

Waiting for the next paid call. Settlement events stream in here as anyone — you, demo visitors, agents — pays through the contract.
A paid article gated by x402 V2 with a one-click Pay button. Demonstrates three SDK features in one route: the access-token extension grants 1 hour of cached access after a paid call, the payment-identifier extension dedupes retries server-side, and the paywall HTML adapter is what a third-party merchant without a React frontend would render.
The article tab uses your already-connected Web3Auth wallet — one click pays, the article unlocks in place. Reload anytime in the next hour; the cached access token serves the article for free.
Settlement runs through SettlementContract.settle(...). Token: DEMO-USDT. 0x925d…a8c6
Hand it to an agent
Spawn a fresh SCW in your browser, fund it from your wallet, and watch it loop through the paid endpoints autonomously. The agent signs its own UserOps from its own EOA; the paymaster sponsors gas; settlement lands on chain. Same flow as a Node script, in your browser tab.
Connect your wallet first. The agent runs from a fresh SCW you fund — your wallet is the bank.
