LeetCode Solution

Parse a single LeetCode community solution post into structured JSON with its author, tags, write-up, extracted code blocks, and engagement counts.

Only the rendered code blocks are returned

Many posts advertise several languages but put the alternatives behind tabs that render one at a time. codeBlocks holds the blocks present in the write-up as served, so a post titled for three languages can come back with blocks in one.

API usage

Add &scraper=leetcode-solution 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/3619262/3-methods-c-java-python-beginner-friendl-x595/' \
  --data-urlencode 'scraper=leetcode-solution' -G
from crawlbase import CrawlingAPI

api = CrawlingAPI({'token': 'YOUR_TOKEN'})
res = api.get(
    'https://leetcode.com/problems/two-sum/solutions/3619262/3-methods-c-java-python-beginner-friendl-x595/',
    {'scraper': 'leetcode-solution'}
)

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/3619262/3-methods-c-java-python-beginner-friendl-x595/',
  { scraper: 'leetcode-solution' }
);
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/3619262/3-methods-c-java-python-beginner-friendl-x595/', scraper: 'leetcode-solution')
data = JSON.parse(res.body)

Example input URL

Any LeetCode community solution post works in the url parameter - the page at /problems/<slug>/solutions/<id>/<post-slug>/. For example:

https://leetcode.com/problems/two-sum/solutions/3619262/3-methods-c-java-python-beginner-friendl-x595/
https://leetcode.com/problems/two-sum/solutions/127810/two-sum-by-leetcode-kwuq/
