01 Live demo

Four Exercism scrapers. One clean JSON each.

The four Exercism scrapers, typed live. exercism-serp lists a track's exercises, exercism-exercise pulls one exercise with instructions, exercism-solutions ranks the community submissions, and exercism-solution returns a single published solution with source. Switch tabs, or hover to pause and read.

02 Capabilities

One API, every corner of Exercism.

Four dedicated scrapers cover the pages that matter: track exercise lists, single exercises, community-solution listings and individual published solutions. The Crawling API renders each page in a real browser, reaches it through residential IPs, and hands you clean HTML or JSON.

tracks

Every language track

exercism-serp turns any track exercise list into JSON: each exercise with its slug, type, title, difficulty, blurb and unlock state, plus the track exercise count.

exercises

Full exercise instructions

exercism-exercise returns a single exercise overview with its title, difficulty and the complete instructions as both text and HTML.

solutions

Community solution listings

exercism-solutions returns a paginated listing of community solutions for an exercise, each with author, language, stars, comments, views, iterations and a snippet.

source code

Full published solutions

Add scraper=exercism-solution to return one published solution with its full source code, iteration history, tests status and author.

proxies

140M residential IPs

Every request rotates a residential IP across 30 geographies and clears bot checks automatically. Nothing to solve, nothing to maintain.

one token

One API for every page

The Crawling API works on any URL, so the same token covers every Exercism track and everything else you crawl. See the live demo.

03 Output

Every solution field, as clean JSON.

Send a solution URL with scraper=exercism-solution and the solution comes back as typed JSON, source code included. Swap in exercism-serp, exercism-exercise or exercism-solutions for lists, instructions and community solutions.

04 How it works

From URL to data in one call.

Every Exercism request moves through the same path. You send a URL, we operate everything in between.

01

Send the URL

Pass any public Exercism URL with your token: a track exercise list, an exercise, a solution listing or a single published solution.

02

Rotate a proxy

A residential IP and geography that reach the site cleanly, drawn from 140M IPs across 30 regions.

03

Render the page

A real browser loads the page so exercises, solutions and code render before capture.

04

Clear anti-bot

The site's bot checks and rate limits are handled automatically. Nothing to solve, nothing to maintain.

05

Return HTML or JSON

The fully rendered HTML comes back, or typed JSON when you add exercism-serp, exercism-exercise, exercism-solutions or exercism-solution.

05 Use cases

What teams build on Exercism data.

USE / 01Training

Code training data & RAG

Feed clean exercise prompts and real published solutions into models, RAG pipelines and coding agents through one API.

USE / 02Benchmarks

Solution benchmarks

Assemble structured solution datasets across languages, with stars, iterations and tests status, for evaluation and benchmarks.

USE / 03Curriculum

Curriculum & catalog sync

Mirror track exercise lists, types, difficulty and unlock order to keep learning platforms and catalogs in sync.

USE / 04Research

Language & style research

Compare how the same exercise is solved across languages and authors to study idioms, patterns and iteration history.

USE / 05Content

Docs & content pipelines

Pull exercise instructions as text and HTML to power tutorials, docs and study guides.

USE / 06Coverage

Any URL, one API

Crawl tracks, exercises, solution listings and single solutions, plus any other site you need.

06 Notes

Good to know when scraping Exercism.

Four scrapers, four page types

exercism-serp reads a track exercise list, exercism-exercise a single exercise, exercism-solutions a community-solution listing, and exercism-solution one published solution with its code.

HTML by default, JSON on request

You get the full rendered HTML. Add scraper=exercism-serp, exercism-exercise, exercism-solutions or exercism-solution for parsed JSON, or parse the HTML yourself.

Solution listings are paginated

exercism-solutions returns page, totalPages, totalCount and solutionCount alongside the solutions array, so you can walk every page for an exercise.

Reach the site from anywhere

Geotargeting across 30 regions and 140M residential IPs means consistent access without managing proxies.

08 FAQ

Exercism scraping questions.

Send any Exercism URL to the Crawlbase Crawling API with your token. Crawlbase rotates a residential proxy, renders the page in a real browser, clears bot checks, and returns the fully rendered HTML. Add a dedicated scraper (scraper=exercism-serp, exercism-exercise, exercism-solutions or exercism-solution) to get structured JSON instead.
Yes. By default the Crawling API returns rendered HTML; add a dedicated scraper to receive structured JSON: exercism-serp for a track exercise list, exercism-exercise for a single exercise, exercism-solutions for a community-solution listing, and exercism-solution for one published solution with its iterations and code.
Track exercise lists, single exercise pages, community-solution listings and individual published solutions, across every language track on exercism.org. The same API works on any other site too.
Crawlbase routes each request through rotating residential IPs across 30 geographies and clears bot checks automatically, so access stays consistent and there is nothing to maintain when the site changes its setup.
exercism-serp returns a track exercise list, each entry with its slug, type, title, difficulty, blurb and unlock state. exercism-exercise returns a single exercise overview and full instructions. exercism-solutions returns a paginated community-solution listing with author, language, stars, comments, views and iteration counts. exercism-solution returns one published solution with its full source code, iteration history and author.
Yes. The exercism-solution scraper returns the full source code of a published solution alongside its iteration history, tests status, star count and author handle.
