What "verified" means for ClaudeBot

For ClaudeBot, "verified" means DataSaaS compares the request IP against Anthropic's published ranges. A request carrying this user agent from any other IP is recorded as unverified.

Track it

ClaudeBot fetches raw HTML and never runs JavaScript, so no browser tag can see it. Install the DataSaaS server-side package to record every request and verify the ones that publish IP ranges.
