description: Wikidata is a free, CC0-licensed knowledge base operated by the Wikimedia Foundation. All public APIs (Wikibase REST, MediaWiki Action, SPARQL Query Service, Linked Data interface, Recent Changes event stream) are free of charge with no paid tiers. Heavy or commercial users are expected to follow the User-Agent and maxlag policies, mirror data via the database dumps, or contract with Wikimedia Enterprise for commercial-grade access.

    description: All Wikidata APIs are publicly accessible at zero cost under the CC0 license. Use is governed by the Wikimedia User-Agent policy, robot policy, and global rate limits; abusive traffic is rate-limited or blocked, and bulk consumers should prefer the database dumps.
