The Web-API, in layman's terms, is "Web server that responds to the data request". * Application Programming Interface
Suppose if, preparing an environment in which anyone can refer / collect the latest information that changes from moment to moment such as "Weather information", "Exchange information", "Stock quotes", "Postal code", "Power usage", at any time hopefully for Free, information systems around the world will evolve more and more. Web-API may be said "foundation technology of data infrastructure".
And the development of "data infrastructure" is the key to develop human society. (It's something like "traffic infrastructure" (roads) that people and vehicles use.)
However, for the time being, there is almost no "useful Web-API" that can be used for free.
In the first place, there is almost no "benefits for the side which continue providing the information". (You can't attach advertisement...) And yet, it must endure against the enormous amount of Requests (+ attacks) from computers around the world. (Even though no doubt that it is "the reason why those are the seeds of new business"...)

In such situation, Japanese Government (National Tax Agency) is going to start an information reference service for "Corporation Number" (Individual Number Act). It is referred to as "Corporation Number system API". It has two major functions. I want them working hard by all means,(at all costs).
- A Obtain corporate information by '13-digit number'
- B Obtain updated corporate information by specifying 'period'
