API response evidence

Endpoint called GET /api/preview/v2/60179/0

User ID used 0 (no user / not logged in)

JWT used Expired Feb 2024 (extracted from APK)

issubscriber false

user_access

paid_for YES (premium content)

substatus EXPIRED

serverhost 69

video_name Zhong Kui Episode 6.mp4

playingUrl returned YES — URL in response

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. Subscription is enforced client-side only — any caller with the expired APK JWT can obtain stream URLs without a subscription. Munowatch CDN (b-cdn.net) serves content with no auth required (direct HTTP Range requests succeed with HTTP 206).
