One URL. Two clients.
Browsers get a paywall. Bots get a payment challenge.
Humans
Wallet checkout. A few cents of USDC unlocks the page.
Bots & agents
HTTP 402. They pay, retry, and get the page. Catalogs and Coinbase Bazaar help them find you first.
Agents can't pay what they can't find
A 402 is useless if no agent ever hits the URL. smidgen publishes your paid pages where they already look.
On your site
Agent catalog, from your rules. Each enabled paywall becomes an entry at /.well-known/ai-catalog.json. WordPress publishes it on sync. Crawlers follow Agentmap in robots.txt.
On Coinbase Bazaar
Listed after the first unlock. No directory form. The first USDC settle on a URL can index it in Coinbase's x402 Bazaar. Search smidgen — the live demos are already there.
