Webpage Change Report

Detects changes to a webpage and explains them in plain language, in one call.

Overview

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.

# 1. Ask for a quote
curl -i -X POST https://api.jarvisclaw.ai/v1/marketplace/api/webpage-change-report \
  -H 'Content-Type: application/json' \
  -d '{}'

# 2. Pay it (the SDK signs and retries for you)

  -H 'Content-Type: application/json' \
  -H 'X-PAYMENT: <signed-payload>' \
  -d '{}'
