Get all known vocab

WaniKani API And Third-Party Apps
1

hi! I am trying to write a script to get all known vocab (whether thats kana, kanji + kana, or just the kanji itself)

I think the way you’re meant to do this is:

but my queries are not returnign vocab / words, just the kanji :thinking:

    url = "https://api.wanikani.com/v2/assignments"

    querystring = {
        "srs_stages": "[1, 2, 3,4,5,6,7,8,9]",
        "subject_types": ["vocabulary", "kana_vocabulary", "kanji"]
    }

    url = "https://api.wanikani.com/v2/subjects"
...
 characters_list = [item['data']['characters'] for item in data['data']]

Anyone know whats wrong or if a script for this already exists?

            results.append(item)

            continue_fetch(json["pages"]["next_url"], headers)
    continue_fetch(request_url, headers)

    narrower = ["subject_types=kana_vocabulary,vocabulary,kanji",
                f"srs_stages={','.join(str(n) for n in range(1, 10))}"]
    narrower_string = f"?{'&'.join(narrower)}"

    subjects = fetch(subject_url, headers, subject_id_pool=subject_ids)

    characters = set([subject["data"]["characters"] for subject in subjects])
    for character in characters:
        print(character)

This includes

Edit: I replaced range(10) with range(1, 10) to prevent items with SRS level 0 from showing up. Previously, this showed items that were unlocked but never studied. I also made the structure a bit simpler. I have also just converted the final group of characters to a set before printing to prevent duplicates. This printed, for example, both 一 (kanji) and 一 (vocabulary), but now it just prints 一 once.
