You can buy either an "Enterprise" licence which does basic firewall and SDWAN, or an "Advanced Security" licence which enables malware scanning, content filtering, etc. There is a more detailed break down:
I understand Cisco Meraki does not have any MX-82 Model as of now. The nearest I can think of is MX 84 which available for now.
MX 84 is a security appliance (UTM).
It offers various services like Web Caching, VPN Server, DHCP Server, VLANs, Content Filtering, L3 & L7 Firewall and many more.... The device can be configured with various features depending on your requirement or network topology.

Thank you very much, but is it possible to buy the Meraki MX 84 and used without the license if yes, the option of web caching will be operational because in reality I need this option to solve a time either little concern about the speed of my network. The cost of the license is high my structure (SME). thanks again
