x402'd

Your agent just made a sale. Did you feel it?

Agent commerce closed the machine loop — payment, receipt, on-chain proof. The human loop is still open: your first agent sale arrives looking like every other bank notice.

You've been x402'd.

We don't make notifications. We translate receipts into feelings. Every line of a cha-ching maps to a field of a verifiable x402 receipt — what sold, for how much, settled on-chain — with an optional public anchor. The feeling is real because the receipt is. The phrase is ours and you'll be using it: you've been x402'd.

Live proof, not a mockup

This is running in production on our own API today. Our first agent sale, 2026-07-11, is anchored on-chain: view the attestation. Our numbers are public at /open.

How it works

  1. Your API emits x402-receipts.
  2. The notify layer renders the moment.
  3. Delivered where you live: email, Slack, Discord, Telegram, webhook.
