I’m not sure of any programs that will do this for you but Lemmy has a pretty nice API that you can use and there are libraries you can use for languages like JavaScript: https://github.com/LemmyNet/lemmy-js-client

import { LemmyHttp } from 'lemmy-js-client

const client = new LemmyHttp( 'https://beehaw.org/' )

const response = await client.search( {
	listing_type: 'Local',
	q: 'https://www.huckmag.com/article/sex-workers-and-the-kink-community-are-fighting-back-against-instagram-deplatforming',
	sort: 'TopNineMonths',
	type_: 'Url'
} )

console.log( response.posts.length ) // Should print '1' to the console

Edit: This can also be done without the library, got me interested and I’ve been playing with it.

This is essentially what the library does when you don’t need authentication:

https://beehaw.org/api/v3/search?listing_type=Local&q=https%3A%2F%2Fwww.huckmag.com%2Farticle%2Fsex-workers-and-the-kink-community-are-fighting-back-against-instagram-deplatforming&sort=TopNineMonths&type_=Url

This is the function they’re using to URL encode the FormData and it just gets pasted onto “https://www.beehaw.org/api/v3/[endpoint]?”:

function encodeGetParams(p) {
    return Object.entries(p)
        .filter(kv => !!kv[1])
        .map(kv => kv.map(encodeURIComponent).join("="))
        .join("&");
}
