Exercism Solution

Parse a single published Exercism solution page into structured JSON with its track, exercise, author, language, iteration history, and full source code.

API usage

Add &scraper=exercism-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://exercism.org/tracks/ruby/exercises/two-fer/solutions/neilnorthrop' \
  --data-urlencode 'scraper=exercism-solution' -G
from crawlbase import CrawlingAPI

api = CrawlingAPI({'token': 'YOUR_TOKEN'})
res = api.get(
    'https://exercism.org/tracks/ruby/exercises/two-fer/solutions/neilnorthrop',
    {'scraper': 'exercism-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://exercism.org/tracks/ruby/exercises/two-fer/solutions/neilnorthrop',
  { scraper: 'exercism-solution' }
);
const data = JSON.parse(res.body);
require 'crawlbase'
api = Crawlbase::API.new(token: 'YOUR_TOKEN')

res = api.get('https://exercism.org/tracks/ruby/exercises/two-fer/solutions/neilnorthrop', scraper: 'exercism-solution')
data = JSON.parse(res.body)

Example input URL

Any single published Exercism solution page works in the url parameter - the page at /tracks/<track>/exercises/<slug>/solutions/<handle>. For example:

https://exercism.org/tracks/ruby/exercises/two-fer/solutions/neilnorthrop
https://exercism.org/tracks/go/exercises/hello-world/solutions/erikschierboom
