□ No challenge detected

Watch a public web page and get a signed webhook the moment a condition becomes true (restock, price drop, appointment slot, launch, content change, HTTP status, a new URL in a sitemap, a new item in an RSS, Atom, or JSON feed); a half-cent recheck that says whether a page changed since the hash you hold; timed wakeups; a durable callback inbox for AI agents whose session ends before the world answers. $0.005 to $2.00 per purchase, USDC on Base or Solana, no account.
