LeetCode Solutions

Parse the community solutions tab of a LeetCode problem into structured JSON with each post title, author, tags, and engagement counts.

Counters are rounded above a thousand

LeetCode abbreviates upvote, view, and comment counts once they pass a thousand - 11.9K, 2.3M. Those are expanded back to integers, so a value like 11900 carries the precision the page showed rather than the exact figure.

API usage

Add &scraper=leetcode-solutions to a Crawling API request. URL-encode the target URL in the url parameter.

curl 'https://api.crawlbase.com/?token=YOUR_TOKEN' \
  --data-urlencode 'url=https://leetcode.com/problems/two-sum/solutions/' \
  --data-urlencode 'scraper=leetcode-solutions' -G
from crawlbase import CrawlingAPI

api = CrawlingAPI({'token': 'YOUR_TOKEN'})
res = api.get(
    'https://leetcode.com/problems/two-sum/solutions/',
    {'scraper': 'leetcode-solutions'}
)

import json
data = json.loads(res['body'])
const { CrawlingAPI } = require('crawlbase');
const api = new CrawlingAPI({ token: 'YOUR_TOKEN' });

const res = await api.get(
  'https://leetcode.com/problems/two-sum/solutions/',
  { scraper: 'leetcode-solutions' }
);
const data = JSON.parse(res.body);
require 'crawlbase'
api = Crawlbase::API.new(token: 'YOUR_TOKEN')

res = api.get('https://leetcode.com/problems/two-sum/solutions/', scraper: 'leetcode-solutions')
data = JSON.parse(res.body)

Example input URL

The solutions tab of any LeetCode problem works in the url parameter - the page at /problems/<slug>/solutions/. For example:

https://leetcode.com/problems/two-sum/solutions/
https://leetcode.com/problems/add-two-numbers/solutions/
https://leetcode.com/problems/valid-parentheses/solutions/
