Building a word of mouth for an API service? What to pay attention to?

Question

Marketing

Good afternoon!
There is a site with a search API (service), on which you need to dial the first line of target "radio operators" who will attract the next, etc.
Resorting to the creation and maintenance of groups in social networks is not an option: there is no target audience there.
Questions:
1. Is it worth posting social media? buttons or capture forms (and which is better)?
2. Is it worth placing a QR code in a modal pop-up layer (on click) and which link is better?
3. What else can be done to get "radio" running at full capacity?
Who and how does - share advice and experience. Thanks in advance!

It doesn't work very well

it works :)
It's not entirely clear what business problem the service solves, and therefore it's not clear how and to whom it can be useful.
Determining the similarity of words is certainly cool, but I can’t imagine a case in which I would turn to a third-party service for this.
If the service can search by my data, then it’s not clear how I can export them to you (such an elasticsearch for the lazy)
In the demo you have an example of a search, and in the description there are other methods.
Look at the https://dadata.ru/ service , they not only have a pretty well implemented search, but also a huge database.
