What services for determining gender and age (without mandatory user authorization on the website) exist (can be paid)?

Question

data mining

Good afternoon. Interested in the API of various external systems where you can get the gender and age of a website visitor.
Of those that I know:

• Yandex.Metrica - very big lag (~40 minutes)
  
• Google Analytics
  

Desirable:

• working in Real-time, that is, they sent a request and received a response for the current user session
  
• preferably not very expensive - the issue of prices is discussed
  

Of the methods of determination, I want those close to reality based on:

• real behavior of sessions, visits to pages, classification of pages and content, time of day, search queries, etc. (it is clear that search engines are the best)
  
• social networks (if they provide such an opportunity without asking to authorize the user on the target site), it can be in the form of a service that has already authorized users through social networks and some other platforms and provides data in real-time upon request without the need to authorize the end user
  

First of all, they are interested in links to the API, a description of the service, and some links to data sources. In the future I will be able to share my real-time service based on data aggregation from several sources.

Answer 1

Hards through the docking station, otherwise it fits. If the docking station is connected to a router, then it will be possible to access data over the network and from other computers.
The price is 5 thousand, the size is about a credit card, the power is 3 W... Well, there is also a docking station, a hard drive, a router, a mouse-clave-monitor...
