FAQ

What happens after I submit?

Your submission enters our review queue. We verify the service is live and matches the description. Most submissions are processed within 24 hours.

How does the payment work?

We use x402 — a gasless EIP-3009 USDC signature on Base. No gas fees for you. You sign a one-time authorization in your wallet; we settle it on-chain.

What if my submission is rejected?

We will provide feedback on why. Common reasons: service not reachable, misleading description, or does not actually implement x402/A2A.

Can I update my listing later?

Yes! Once approved, contact us to update your listing details. Updates are free.
