What "verified" means for Claude-SearchBot

For Claude-SearchBot, "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

Claude-SearchBot 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.
