# YouTube-Internal-Clients

A script that discovers hidden internal clients of the YouTube (Innertube) API using bruteforce methods. The script tries `clientNames` with a sequential ID enumeration and crosses them with known `clientVersions`.
The goal was to find a client that has no age restrictions implemented. With success.
