Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Class Central Scraper Scrape **Class Central** — the course meta-search engine that indexes courses from Coursera, edX, Udemy, YouTube, Google, IBM, and 100+ other providers, with independent ratings and reviews. Search by keyword, browse by subject or provider, pull curated "Best of All Time" lists, or fetch full course detail (rating, reviews, syllabus, effort, pricing). HTTP-only, no login, no proxy required. ### What this actor does - **Six modes:** `search`, `bySubject`, `byProvider`, `byUniversity`, `collection`, `courseDetail` - **92 curated subjects** (Computer Science, Data Science, Business, Health, Humanities, and more), **104 providers** (Coursera, Udemy, YouTube, Google Skills, Microsoft Learn, MIT OpenCourseWare, ...), and **~100 universities/institutions** (Stanford, MIT, Oxford, Harvard, ...) as ready-to-pick dropdowns - **Filters:** level (beginner/intermediate/advanced), language (62 languages), duration/effort bucket, free-only, certificate-only, career-certificate-only, university-only, minimum rating, minimum number of ratings, and sort order - **Course detail mode** returns rating, review count, a sample of real user reviews, syllabus topic outline, effort/duration, session type, pricing, and institution (when university-affiliated) - **Empty fields are omitted** — you won't see `null`, `""`, or `[]` anywhere in the output ### Output: course listing (mode = `search` / `bySubject` / `byProvider` / `byUniversity` / `collection`) - `courseId`, `title`, `slug` - `courseUrl` — canonical Class Central course page - `imageUrl` — course thumbnail - `description` — one-line course teaser - `format` — `course`, `credential` (nanodegree/professional certificate), `specialization`, etc. - `level` — `beginner` / `intermediate` / `advanced` - `language` — course language - `provider`, `providerUrl` — the platform hosting the course (Coursera, Udemy, ...) - `institution` — university/partner name, when the course is university-affiliated - `subject` — Class Central's subject tag for this course - `rating` (0–5), `numRatings` - `isFree`, `hasCertificate`, `isUniversityCourse` - `sessionType` — `Self-Paced` or a specific session/date window - `pricingLabel` — e.g. `Free Online Course`, `Paid Course` - `effort` — e.g. `109 hours`, when Class Central shows a workload estimate - `rank` — 1-based position in this run's result order - `sourceMode` — which mode produced this record (`search` / `bySubject` / `byProvider` / `byUniversity` / `collection`) - `recordType: "courseListing"`, `scrapedAt` ### Output: course detail (mode = `courseDetail`) - `courseId`, `slug` - `title`, `courseUrl`, `imageUrl`, `description` - `provider`, `providerType` (e.g. `Nanodegree`), `currency`, `price` (when a listed price exists) - `institution`, `institutionUrl` — university/academic partner and its Class Central page, when the course is university-affiliated (e.g. Coursera courses run by University of Michigan) - `pricingLabel`, `languages`, `certificateLabel`, `certificateAvailable` - `effort` — e.g. `109 hours` - `sessionType` — `Self-Paced` or session dates - `level` - `rating` (0–5), `numRatings` - `subjectTags` — subject/topic breadcrumb leaves for this course - `syllabus` — ordered list of syllabus topic titles - `reviews[]` — sample of real user reviews: `author`, `date`, `text`, `rating` - `recordType: "courseDetail"`, `scrapedAt` ### Input | Field | Type | Default | Description | |---|---|---|---| | `mode` | string | `search` | `search` / `bySubject` / `byProvider` / `byUniversity` / `collection` / `courseDetail` | | `searchQuery` | string | `python` | Keyword query (mode=search) | | `subjectSlug` | string | – | Subject to browse (mode=bySubject);

unrated courses excluded | | `minReviews` | integer | – | Only courses with at least this many ratings; unrated courses excluded | | `sortBy` | string | `relevancy` | `relevancy` / `highestRated` / `lowestRated` / `recentlyAdded` | | `maxItems` | int | `30` | Hard cap on emitted records (1–500) | #### Example: search with filters ```json { "mode": "search", "searchQuery": "machine learning", "level": "beginner", "freeOnly": true, "maxItems": 40 } ```` #### Example: browse a subject, sorted by rating ```json { "mode": "bySubject", "subjectSlug": "data-science", "sortBy": "highestRated", "certificateOnly": true, "maxItems": 50 } ``` #### Example: browse a provider's catalog ```json { "mode": "byProvider", "providerSlug": "coursera", "language": "spanish", "maxItems": 30 } ``` #### Example: browse a university's catalog, highly-rated only ```json { "mode": "byUniversity", "universitySlug": "stanford", "minRating": 4.5, "minReviews": 20, "maxItems": 30 } ``` #### Example: curated "Best of All Time" list for one subject ```json { "mode": "collection", "collectionSlug": "top-free-online-courses", "subjectSlug": "cs", "maxItems": 20 } ``` #### Example: full detail for specific courses ```json { "mode": "courseDetail", "courseUrls": [ "https://www.classcentral.com/course/udacity-intro-to-programming-nanodegree--nd000-18207" ] } ``` ### Use cases - **Edtech curriculum research** — discover and compare courses across every major MOOC provider in one pass - **Market intelligence** — track which providers dominate a subject, and how their courses are priced and rated - **Content aggregation** — build a course-discovery feed filtered by level, language, or free/paid status - **Review mining** — pull real learner reviews for sentiment analysis or course-quality benchmarking - **Corporate L\&D** — source free, certificate-bearing courses for employee upskilling programs ### FAQ **What is the data source?** The public [classcentral.com](https://www.classcentral.com) website — a third-party course meta-search engine. This actor is not affiliated with Class Central or any course provider. **Does this require login or an API key?** No. All modes work against Class Central's public pages with no authentication. **Why are some fields missing on some courses?** Class Central sources course metadata from each provider, and not every provider supplies every field (e.g. price, institution, or duration). This actor omits any field it can't populate rather than showing an empty value. **What's the difference between `subject` (in course listings) and `subjectTags` (in course detail)?** `subject` is the single subject tag Class Central assigns for catalog placement. `subjectTags` (course detail only) is the fuller set of topic breadcrumbs the course is filed under. **Are the reviews the full review history for a course?** No — `reviews[]` returns the sample of reviews shown on the course's main page (up to 20), not a fully paginated review archive. **How fresh is the data?** Every run scrapes Class Central live; there is no caching on this actor's side. **Why do `courseUrl` / `providerUrl` links return 403 when fetched with a plain script?** Class Central fronts its pages with a TLS-fingerprint check that blocks simple HTTP clients (curl, requests, httpx) while allowing real browsers through transparently. Every URL in the output is a real, working Class Central page — opening it in any normal web browser works immediately. This actor itself uses a browser-matching HTTP client internally so it is unaffected. **Can I filter by duration/effort?** Yes — the `duration` input filters by total workload bucket (`<30` minutes up to `10+` hours), matching Class Central's own catalog filter. `effort` (the human-readable workload string, e.g. `109 hours`) is also available as an output field on every listing and detail record. **What's the difference between `provider`/`providerUrl` and `institution`/`institutionUrl` in course detail?** `provider` is the platform hosting the course (Coursera, Udacity, edX, ...). `institution`/`institutionUrl` is the university or academic partner that authored the course content, when applicable (e.g. a Coursera course run by the University of Michigan). Not every course has an institution — many platform-original courses (Udacity nanodegrees, YouTube videos) have no academic affiliation, so the field is omitted for those. # Actor input Schema ## `mode` (type: `string`): What to fetch. ## `searchQuery` (type: `string`): Free-text keyword search, e.g. `python`, `machine learning`, `public speaking`. ## `subjectSlug` (type: `string`): Class Central's curated subject taxonomy.
