Homepage-level, datacenter-IP snapshot, June 13, 2026.
This is a homepage-level snapshot and can be inaccurate or out of date — anti-bot vendors update their models continuously, deep pages are usually more protected than the homepage, and difficulty is IP-sensitive: a site can read differently from a clean vs a flagged IP and even flip over time. Treat it as a directional signal, not a guarantee.
The homepage is the open front door. On a healthcare site the valuable pages behave differently — here's the plan to characterise heart.org before you build.
Article / entry
usually openReference content is usually open.
Search
rate-limitedOpen but rate-limited at volume.
Find a real deep URL cheaply from the site’s robots.txt and sitemap.xml, then run each through the anti-bot checker. This is an advisory based on the category and heart.org’s homepage result — detect the wall, never try to pass a login.
