All 9 App Store endpoints

Click any endpoint to open its console: fill the parameters and try it live — the payable URL opens in a new tab, ready for a browser wallet.

Top up once — then hammer all 9 endpoints with one key

One x402 payment funds a credit balance. Every call after that is a plain Bearer request: no signing, no chain round-trip, more requests per second.
