Hello. I am writing a crawler and a parser to obtain structured information from Wiktionary pages

However, i saw that a site called as yourdictionary already have structured information from Wiktionary

So i wonder, are there any APIetc that does provide structured information? Or they have written their own custom crawler and parser?

For example

page : https://en.wiktionary.org/wiki/game

some structured information from yourdictionary . com

So i dont want to waste my time if any easier way to obtain in such time because i believe i will be writing a lot of cases

To sum up, my question is, are there any way to obtain machine readable format of pages?

Or i have code my own custom parser?
