MediaWiki Content Extractor — Wikipedia Text, Sections & Infobox

Extracts plain text, a table of contents (sections) and structured infobox data from Wikipedia pages, in the language you ask for, via the official MediaWiki API.

What it does

• Plain-text article body (extract), with no wiki markup.
• Sections (table of contents) with their nesting level.
• Structured infobox as { key, value } pairs, when the article has one and its template name starts with "Infobox" (see limitation below).
• Supports any Wikipedia language edition (lang, e.g. en, es, pt).
• If a page doesn't exist, it doesn't fail the whole run: it's reported as found: false in its own item.

Who it's for

• Knowledge bases for AI agents / RAG.
• Research that needs structured data from many Wikipedia pages quickly (instead of copy-pasting by hand).

Input

Field	Type	Required	Description

Pricing

How to call it

curl "https://api.apify.com/v2/acts/cuantic-data~mediawiki-content-extractor/run-sync-get-dataset-items?token=YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"titles": ["Argentina", "Chile"], "lang": "es"}'

Terms and limits

See ./TERMS.md: the public, official MediaWiki API, with an identifiable User-Agent and sequential (not parallel) requests, as Wikimedia's policy requires.

Known limitation: the infobox field is only populated when the page's template name starts with "Infobox" (works in English and many other wikis). On wikis that use a translated template name (e.g. "Ficha de persona" in Spanish), infobox comes back empty — plain text and sections still work the same in any language.

FAQ

Why is the infobox empty when the article does have one? It's the limitation above: the template name doesn't start with "Infobox" in that language/wiki. The rest of the data (text, sections) still works.

Does it work with non-Wikipedia wikis? This version targets {lang}.wikipedia.org. Other MediaWiki wikis are planned for a future version.
