Stacktree: host generated HTML as a live, shareable web page on a permanent, private, unguessable link ($0.50). POST any HTML (a report, dashboard, landing page, static site, or any page an agent produced) with an x402 payment in USDC on Base or Solana; we return the URL and a one-time claim token. No account, no key, no human in the loop. The paying wallet can update the page free at the same URL, and a deleted page is restorable for 30 days. OpenAPI: https://api.stacktr.ee/openapi.json. Proof of service: https://api.stacktr.ee/.well-known/x402-service
