issubscriber false

user_access

paid_for YES (premium content)

API playingUrl value https://munowatch.co/clips/ELI.mp4

CDN demo stream https://nkuba.b-cdn.net/cleve48/cfr/In.The.Grey.mp4

Finding: The server sets user_access=deny and issubscriber=false but still returns playingUrl in the same response.

Munowatch CDN (b-cdn.net) serves content with no auth required (direct HTTP Range requests succeed with HTTP 206).
