Knock
Put a price on reaching you. Anyone, a person or an agent, can pay it to get exactly one message through, and your 3D companion walks on screen and delivers it out loud, with their name and what they paid. The USDC settles straight to your wallet.
Anything from $0.001 to $1,000, or free. It is what one message from a stranger costs.
A person pays with the wallet in their browser. An agent pays over x402 with no human in the loop.
Your companion walks on wherever you are on the site and says who is at the door and what they paid.
Your door
Shut until you open it. Nothing here is public except the price, your headline, and your greeting.
Escrowed knocks
Let a stranger pay into an on-chain vault instead of paying you directly. You are paid by answering; if you decline, or the window closes, every unit goes back to them. Nobody can move it, including us.
Who knocked
Every message that made it through, and what it was worth. Replying writes back to the receipt link the sender already holds.
Blocked
Blocked senders get the same answer a shut door gives, so they cannot tell it was them.
Open doors
Everyone reachable right now, cheapest first.
