Wikimedia, LLC

Wikimedia, LLC is a single-member limited liability company of the Wikimedia Foundation, the 501(c)(3) nonprofit organization that hosts Wikipedia and other free knowledge projects. The company operates Wikimedia Enterprise, a product built to make Wikimedia project data — created by volunteers around the world — accessible at scale through enterprise-grade APIs. Its stated purpose is to serve developers, researchers and companies building applications in AI, machine learning, search and data science, while helping sustain the free knowledge ecosystem by keeping high-quality data open and accessible. Wikimedia Enterprise offers three main API collections: the Snapshot API, which lets customers download an entire Wikimedia project in any language as a compressed database dump file, retrievable chunk by chunk; the On-demand API, which fetches a single article by name and returns its latest revision in a single HTTP request, with filters for projects, languages and fields; and the Realtime API, which streams every edit, creation and deletion as it happens, also available as hourly batch files. All three collections return the same JSON schema, so customers do not need to switch parsers between them. A distinguishing feature is the Structured Contents Initiative, which pulls infoboxes, sections, tables, citations, references and images out of raw wikitext and HTML and returns them as machine-readable JSON, removing the need for custom parsers or regex. According to the company's own materials, its APIs cover more than 130 million pages across more than 920 Wikimedia projects and more than 350 languages. Free tiers are available, including monthly snapshots, a monthly quota of article lookups, and beta Structured Contents snapshots; paid upgrades add daily snapshots and parsed Structured Contents, with realtime streaming priced through sales contact. Wikimedia Enterprise is positioned as a commercial product within the wider Wikimedia movement. The Wikimedia Foundation separately maintains free and public tools and services such as the MediaWiki Action API, Wikimedia Cloud Services and Wikimedia database downloads. Wikimedia, LLC's operating principles, governance and community discussions are documented on Meta-Wiki, and technical infrastructure details are published on MediaWiki.org. The brand's public identity is closely tied to the Wikimedia family of logos and to the Wikimedia Enterprise logo, which is available in an official press kit.

Wikimedia, LLC exists as a corporate vehicle within the Wikimedia movement. It is described in official materials as a single-member limited liability company of the Wikimedia Foundation, the 501(c)(3) organization that hosts Wikipedia and other free knowledge projects. Wikidata records the entity simply as a subsidiary of the Wikimedia Foundation. The company's public-facing activity centers on Wikimedia Enterprise, which is presented as a product of the Wikimedia Foundation rather than a separate commercial venture. Wikimedia Enterprise was built to make Wikimedia project data — created by volunteers around the world — accessible at scale through enterprise-grade APIs. Its APIs deliver pre-parsed, machine-readable and structured content intended to help teams move faster from ingestion to production, and they include data quality signals and support for developers, researchers and companies building applications in AI, machine learning, search and data science. A central element of the offering is the Structured Contents Initiative, which extracts infoboxes, sections, tables, citations, references and images from raw wikitext and HTML and returns them as machine-readable JSON. This removes the need for customers to write custom parsers or regex. The API portfolio is organized into three collections — Snapshot, On-demand and Realtime — all returning the same JSON schema. Free tiers include monthly snapshots, a monthly quota of article lookups, and beta Structured Contents snapshots; paid upgrades add daily snapshots and parsed Structured Contents, while realtime streaming is priced through sales contact. Wikimedia Enterprise is framed as a way to ensure the sustainability of the free knowledge ecosystem by keeping high-quality data open and accessible for everyone. The Wikimedia Foundation separately maintains free and public tools and services, including the MediaWiki Action API, Wikimedia Cloud Services and Wikimedia database downloads. Governance, operating principles and community discussions for Wikimedia Enterprise are documented on Meta-Wiki, and technical infrastructure details are published on MediaWiki.org. The brand maintains an official press kit with Wikimedia Enterprise logos.
