This testing feature establishes a real x402 paywall on Base mainnet. The cost is 0.01 USDC, which you will receive back to the address entered below; if you enter your own address the fee will go from you (as client) back to yourself (as server).
This paywall is built with the Primer x402 SDK. You can easily build your own - see our documentation. Payments are processed by the Primer facilitator.
Recommended: try to access the paid content once without Primer Pay installed/enabled, then again with it active.
