This website contains age-restricted materials including nudity and explicit depictions of sexual activity.
By entering, you affirm that you are at least 18 years of age or the age of majority in the jurisdiction you are accessing the website from and you consent to viewing sexually explicit content.
You can technically just make yourself a mod of your own private subreddit, then NSFW works fine with the API. It works with RedReader. I still use Reddit a bit for very niche subreddits.
