Content Signals (TDMRep) Checker
Look for a TDM Reservation Protocol header or /.well-known/tdmrep.json policy file.
TDMRep lets a publisher reserve text-and-data-mining rights through an HTTP header, an HTML meta tag, or a policy file at /.well-known/tdmrep.json. This check looks for all of those. It is an opt-in W3C Community Group convention, so not publishing one is the norm, not a problem.
This is one of the checks the AI Agent Readiness Checker scores under Bot Access Control, and it can also be run on its own for any URL.
