Shopping agent from Amazon

# Rufus (shopping assistant)

In short

Rufus (shopping assistant) is Amazon's shopping agent. Rufus has no robots.txt token, so robots.txt cannot address it and the crawl cannot measure a block rate. The operator publishes nothing a site can check. Kept as a row because merchants ask; any web fetch it triggers would surface as Amzn-User if it follows Amazon's documented fetcher.

## Allow and refuse lines

This agent has no robots.txt token, so there are no lines to copy. Without a token, a published list or a signature, a site owner cannot tell it from an ordinary visitor by request alone.

Refusing or allowing in robots.txt states a preference. Enforcement of a refusal belongs in your WAF; see how to verify the identity above.
