Check if a word exists in a dictionary?

Question

API

Hello dear all.
The essence of the question is this - the spouse plays the game of composing words from possible letters, such as a crossword puzzle.
I want to write an application in js, to which you feed variations of letters, and it goes through all possible options and checks the online existence of a word.
Are there any online dictionaries that can be accessed via the API and feed words and get true / false in response, or something like that. Please send.

Answer 1

Take a bigger dictionary, take any database and search for words with a query like '%w%r%d'.
Offline solution with minimum coding

Answer 2

Just a dictionary won't work.
It will be necessary to throw out unnecessary parts of speech from there: particles, conjunctions, verbs, participles ...
I did that.
But then I had to manually clean it up
