Vendor profile, agent-pay builder
thirdweb
In short
thirdweb lets developers charge per call for an API endpoint without API keys, with payments in tokens that follow the x402 specification and settle through server wallets on an open-source engine. Sellers set a price per request, with no billing system to build. The x402 product accepts no card payments, and the text read shows no fee schedule.
