They provide per-call fee-based web services. I've looked into them when they published. I've asked for pricing and privacy months ago but only got a generic reply.
Before you judge, you may also want to check out the similar services provided by Google:

and Microsoft:

I commented on this several times in recent posts: The availability of such A.I. based services was one of the driven factors for the massive amount of work that went into the embedded IMWS in IMatch 2017 and the entire app ecosystem.
This groundwork will allow me to integrate such services much easier. From face recognition to license places, from text recognition to automatic mood and sentiment analysis. Runner numbers for sports photographers etc.
Of course payment will be a challenge. Excire does not publish prices but Google and Microsoft do. This will given you an impression of how much this costs.
Furthermore, these services require authentication (A "key", like for Google Maps or Bing). I can either let the users insert they own keys so they deal with Excire, Google, MS themselves. Or I route this through a proxy server I need to setup so I can use my own API key (in secret) and I need to cover the cost - and charge users of course for the service.
I think this will be one of the challenges with integrating such 3rd party services into IMatch. And of course privacy. If a user wants to use these services he has to allow IMatch to send his images (or thumbnails) to Excire, Google, Microsoft, Frauenhofer or whoever.
