Examples

Things people put behind a link

Each card is a live pattern — load one into the builder above to see its 402.

Agents

Charge AI agents

Crawlers and agents carry wallets now. A 402 is the one paywall they can pay on their own — no login wall to get stuck behind, no key to provision.

Files

Multi-gigabyte artifacts behind one link. Price the download itself, not a monthly plan.

How it works

Three steps, in this order

Settlement only ever happens after the buyer already holds what they paid for.

  1. 01

    They hit your link. The gateway answers with a price. Your server is never touched.

  2. 02

    They approve it. One signature in their wallet — no account, no card, no form.

  3. 03

    You have the money. Straight to your address, on Base, in seconds.
