Subreddit details

When to use this

Use it to size up a community before posting: weekly visitors and contributions, rules and description. There's no subscriber count (reddit.com no longer shows it); weekly_active_users is the closest measure.

Stats and settings for one subreddit: the numbers reddit.com shows on the community page, numbered rules, icon, banner and creation date. Pass subreddit or a Reddit url.

Unknown or private subreddits return 404 not_found.

Parameters

All parameters go in the query string.

Example request

Replace YOUR_API_KEY with your key, or set LURKAPI_KEY for the code. Get a free key.

curl "https://api.lurkapi.com/v1/reddit/subreddit/details?subreddit=marketing" \
  -H "x-api-key: YOUR_API_KEY"

const params = new URLSearchParams({
  subreddit: "marketing",
});
const res = await fetch(`https://api.lurkapi.com/v1/reddit/subreddit/details?${params}`, {
  headers: { "x-api-key": process.env.LURKAPI_KEY },
});
const data = await res.json();
if (!data.success) throw new Error(`${data.code}: ${data.error}`);
console.log(data);

import os
import requests

res = requests.get(
    "https://api.lurkapi.com/v1/reddit/subreddit/details",
    params={
        "subreddit": "marketing",
    },
    headers={"x-api-key": os.environ["LURKAPI_KEY"]},
    timeout=60,
)
data = res.json()
if not data["success"]:
    raise RuntimeError(f"{data['code']}: {data['error']}")
print(data)

Example response

A real response from this endpoint, captured from the live API and trimmed to a couple of items. Strings over 96 characters (mostly signed media URLs) are cut short and end in ….

{
  "success": true,
  "credits_remaining": 994,
  "credits_charged": 1,
  "subreddit_id": "t5_2qhmg",
  "display_name": "marketing",
  "weekly_active_users": 70309,
  "weekly_contributions": 965,
  "rules": "1. Advertising, Self-Promotion, & Spam (Permanent Ban)\nIf you want to ad…",
  "description": "For marketing communications + advertising industry professionals to dis…",
  "header_img": "https://styles.redditmedia.com/t5_2qhmg/styles/bannerBackgroundImage_y1x…",
  "icon_img": "https://styles.redditmedia.com/t5_2qhmg/styles/communityIcon_amdb6rj8w5p…",
  "created_at": "2008-03-23T18:17:57.000Z"
}

Response fields

Every field of a successful response. [] marks a list: a[].b is the b of each item in a. nullable fields can be null; optional fields can be missing.

Caching and freshness

Responses are cached for up to 1 hour, so a repeat call within that window can return the same data. It still costs 1 credit.

Errors

Errors return { success: false, error, code, docs } with the HTTP status below. Validation errors, 401/402/429 rejections and 5xx failures are free; not_found is charged (how charging works). All error codes.

Use it in Claude

Once LurkAPI is connected to Claude, this endpoint is the reddit_subreddit_details tool. Ask in plain English, for example:

Use LurkAPI's reddit_subreddit_details with subreddit "marketing" and summarize what you find.

Claude calls reddit_subreddit_details with arguments like these, and each call costs 1 credit:

{
  "subreddit": "marketing"
}

Tool results skip nulls and empty lists to save tokens.
