NAME

webpage-change-report — detects changes to a webpage and explains them in plain language, in one call

SYNOPSIS

POST https://x402.agentutility.ai/webpage-change-report
     Content-Type: application/json
     X-PAYMENT:    <signed-transferWithAuthorization>

     { ... }

↳ first call → 402 Payment Required. Sign USDCtransferWithAuthorization, retry with theX-PAYMENT header.

DESCRIPTION

Detects changes to a webpage and explains them in plain language, in one call. Give it a URL (plus optional previous_hash or previous_text baseline and CSS selector scope) and get back the changed flag, content hash, added/removed line diff, and an LLM summary of what actually changed, ready to drop into an alert or agent decision. Ideal for competitor monitoring, policy-change tracking, status-page watching, changelog digests. Composite: one call runs webpage-diff first, then summarize-text over the diff. Use it as a website change monitor, page-watch + diff digest, TOS-policy change explainer, or price-page monitor with narrative.
