Does Lemmy allow bots? Is there an API?

I'm sketching out an idea for a readability assessment program. It will report the education level required to comfortably read a body of text using formulas, Dale-Chall being the most significant, that count length of sentences, what level of vocab a word is considered to be, etc. I was inspired by the word counter website I always paste my essays into. When it's done, I would like to plug it into APIs for it to be used on Lemmy, Mastodon, and Discord.
