Methods and systems for monitoring content subscription usage

In some aspects, control circuitry receives, at a content provider server that is associated with a first subscription service, a first authentication key from a content aggregator server that is associated with a second subscription service, prior to the user subscribing to the first subscription service. The control circuitry generates and stores, at the content provider server, the first user account after comparing the first authentication key to acceptable authentication. In response to storing the first user account, the control circuitry receives a request from the content aggregator server to subscribe the user to the first subscription service, wherein the request includes a second authentication key. The control circuitry compares the first authentication key to the second authentication key, and in response to determining that the first authentication key matches the second authentication key, validates the first user account and grants access to the first subscription service through the first user account.
