default	NIP-89	The role of NIP-89 on using Data Vending Machines

NIP-89 defines application recommendation and application handler events.

Data Vending Machines make extend use of these capabilities; DVMs should announce their capabilities by creating an application handler event with a k of the handled job request kind.

A kind:31990 (application handler) event should use it's content profile data to explain to an end-user its specific characteristics.

Clients SHOULD show this information as a way to allow users to choose the specific DVM they want to use.

This is where the long-tail of DVMs can be explored.

Example

DVM supporting kind:5100 -- in Dali style

This NIP-89 acts as a sales-pitch for the DVM to explain to a user exactly what they can expect from interacting with this DVM
