Update, 25 Apr 2026: Trimmed conceptual sections in favor of the new Wikidata API project data page.
Wikidata’s structured knowledge is now available through Wikimedia Enterprise. These new Beta Wikidata API endpoints are part of the On-demand and Realtime APIs, giving you access to the world’s largest open knowledge graph through a high-availability, production-scale interface built for commercial volume, using the same API token you already use for Wikipedia, Wiktionary, Wikivoyage, and more.
Over the past two years, Wikimedia Deutschland and Wikimedia Enterprise have closely collaborated to explore how Wikidata’s structured data can be included in Wikimedia Enterprise APIs in a way that reflects our shared mission and responsibilities.
If you’re already using Wikimedia Enterprise to retrieve Wikipedia articles, you’re closer than you think. Every article response already includes a QID field that these new endpoints can act on directly. All with the same token and no additional setup. To learn more about how Wikimedia Enterprise and Wikimedia Deutschland are jointly working to improve access to free structured knowledge, see WMDE’s statement.

The New Wikidata API Endpoints
We’ve designed our new Beta Wikidata endpoints to fit directly into your development workflow, whether you need a single fact or a real-time stream of global updates. The integration starts with data you’re already receiving: every Wikipedia article response from Wikimedia Enterprise already includes an entity_id field containing the QID for that article’s subject. Pass that QID to /v2/wikidata/items/{QID} to retrieve the full entity record, including entity.sitelinks. The entity sitelinks map that topic to corresponding article titles across every Wikipedia language edition. Until now, retrieving the same topic across language editions meant already knowing the exact article title in each language. With Wikidata sitelinks, a single QID returns the correct article title for every available language edition, so you can retrieve exactly the article you need without any manual title research.
Our endpoints also include the English label for every Item and Property identifier in the payload, and you can extract all of the other language labels using the Labels List endpoint. This way, your knowledge base is always populated with English human-readable labels, and you can use the List Labels endpoint whenever you want to expand multilingually.
| Endpoint | Primary Purpose | Key Identifiers |
|---|---|---|
| On-demand endpoints | ||
| Item Lookup | Get all data and metadata of the last revision of an item: revision info, labels, descriptions, statements, sitelinks. | Q-number (e.g., Q42: Douglas Adams) |
| Property Lookup | Retrieve all information about a property, a single category that connects statements. | P-number (e.g., P106: occupation) |
| Labels List | Translate machine IDs into human-readable text in any language. | Q- or P-numbers |
| Realtime endpoints | ||
| Realtime Stream | A “firehose” of every update, deletion, and change in Wikidata as it happens. Every Realtime edit event also includes the full entity data payload, so you can build your internal knowledge base as changes happen in real-time. | N/A |
How to use Wikidata API endpoints
Use the Item Lookup endpoint to get all metadata and statements about the English computer scientist Tim Berners-Lee (Q80):
curl -L "https://api.enterprise.wikimedia.com/v2/wikidata/items/Q80" -H "Authorization: Bearer ACCESS_TOKEN"Use the Property Lookup endpoint to get all information about the property ‘architect’ (P84), the property used to connect a building or other architectural object with the person or architectural firm responsible for designing it:
curl -L "https://api.enterprise.wikimedia.com/v2/wikidata/properties/P84" -H "Authorization: Bearer ACCESS_TOKEN"With the Labels List endpoint, you can retrieve all of the multilingual human-readable labels for the country of Belgium (Q31):
curl -L "https://api.enterprise.wikimedia.com/v2/wikidata/labels/Q31" -H "Authorization: Bearer ACCESS_TOKEN"To stream every edit to Wikidata in real time (available on paid plans), connect to the Realtime Stream:
curl -L "https://realtime.enterprise.wikimedia.com/v2/wikidata" -H "Authorization: Bearer ACCESS_TOKEN"How to Access the Wikimedia Enterprise Wikidata APIs
Wikidata is now available through the Wikimedia Enterprise On-demand and Realtime APIs. Free accounts have access to On-demand endpoints immediately. Don’t have an account yet? Sign up for free. Wikidata snapshots are not yet available through the Snapshot API. We’ll announce when that changes.
For higher volume needs or Realtime API access, contact our sales team.
More on Wikidata
Wikidata is the structured data layer behind Wikipedia, Wikivoyage, Wiktionary, and every other Wikimedia project. It stores knowledge as Items, Properties, and Values in a graph database, with over 120 million entities connected by typed statements like Q42 → P31 → Q5 (Douglas Adams → instance of → human). Every concept gets a unique identifier, every fact is verifiable, and the entire graph is released under CC0 for any use, commercial or otherwise.
That structure is what makes Wikidata uniquely useful for entity linking, deduplication, classification, authority control, and grounding LLMs and RAG systems in verifiable facts. For a full breakdown of the data model, what’s inside each API response, example payloads, and common use cases, see our Wikidata API project data page.
Get Started
Wikidata’s addition to the Wikimedia Enterprise API suite reflects two years of collaboration between Wikimedia Enterprise and Wikimedia Deutschland. These Beta endpoints are the first step. As the integration matures, we’ll continue to announce new capabilities here. We warmly welcome any feedback you may have, either through the Meta-wiki talk page or your customer success representative.
