SYNOPSIS
POST https://x402.agentutility.ai/watch-page
Content-Type: application/json
X-PAYMENT: <signed-transferWithAuthorization>
{ ... }↳ first call →
402 Payment Required. Sign USDCtransferWithAuthorization, retry with theX-PAYMENT header.DESCRIPTION
Monitors a webpage for changes and remembers the state server-side: caller picks a watch_id and the server stores the page's hash + text in KV. On each subsequent call returns a changed flag, added/removed lines, and an LLM-summarized diff (Morpheus mistral-31-24b). Unlike webpage-diff (caller must remember prior hash), this endpoint owns the state. KV TTL: 365 days. Use it as a stateful page-watch with memory, URL change detector, TOS-policy diff, price-page tracker, status-page watcher, content monitor, or persistent webpage diff.
