A plain HTTP client reaches it — no managed anti-bot detected.

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This is a homepage-level snapshot and can be inaccurate or out of date — anti-bot vendors update their models continuously, deep pages are usually more protected than the homepage, and difficulty is IP-sensitive: a site can read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 other site the valuable pages behave differently — here's the plan to characterise apollo.io before you build.
Primary detail page
variesThe valuable content page — test it directly, not the homepage.
Search / listing
rate-limitedListing/search is the first to throttle or challenge.
Account / login
login wallAnything behind sign-in is not a public surface.
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 apollo.io’s homepage result — detect the wall, never try to pass a login.
