change=unchanged / first-seen rows so you can see coverage
State kept in the Actor key-value store

Input

Field	Required	Notes
`urls`	yes	1–30 public `https://` URLs
`css_selector`	no	Optional text window hint (best-effort substring)

  "urls": [
    "https://example.com/pricing"
  ]
}

Output example

  "url": "https://example.com/pricing",
  "change": "changed",
  "fingerprint": "a1b2c3d4e5f6",
  "observed_at": "2026-08-13T12:05:00Z"

How to run this page monitor

Schedule every 15–60 minutes. Compare runs over a day — that history is the product.

Pricing

Limits

Public HTTPS only (no login walls, no bot-blocked sites guaranteed)
Fingerprint is content-based; tiny HTML noise can flip a hash
