Tizona Intelligence

tizona.venusberg.workers.dev · Tizona Intelligence

Verification and routing for autonomous agents: check whether a crawler is who it claims (a published IP range or a Web Bot Auth signature) and whether an email is deliverable; route a data purchase to the best proven provider and pay only on delivery. Plus Australian business-identity and entity-matching tools. Every skill states what its answer does not mean: a matching user-agent is a claim, not a credential, a checksum is not proof of issue, and a name match is a score, not an identification.
