Source: https://gtmetrix.com/.well-known/ai-catalog.json, this publisher's own file. Identifiers are reproduced exactly as published. Note: this is the pre-v0.91 path. The specification renamed the manifest to /.well-known/ard.json, and most of the ecosystem still serves the older name. None of these endpoints has been probed for reachability yet, so nothing here says whether they answer. "Answers" and "no response" describe only whether an endpoint replied when last probed: services go down and come back, and an entry is demoted rather than removed. None of this is a trust, quality or safety rating.
