Google-CloudVertexBot
Crawls sites at the request of Google Cloud customers building Vertex AI Search applications. It only fetches domains a customer has configured, so a hit means someone is building an AI search product over your content.
Verification
Operator documentation: https://cloud.google.com/generative-ai-app-builder/docs/configure-web-crawling
A user agent is a claim, not a proof: any client can send any name. Where an operator publishes IP ranges, a reverse lookup is the only way to tell a real visit from an impersonation.
