  Wikipedia and all native Wikimedia Foundation APIs (MediaWiki Action API, MediaWiki Core REST API,
  Wikimedia REST API v1, Wikidata Query Service) are free of charge under the Wikimedia API usage
  guidelines - the only requirement is a contactable User-Agent and respect for rate limits. The
  commercial tier is operated separately by Wikimedia LLC under the Wikimedia Enterprise brand,
  with a Free developer plan and a Paid plan whose pricing is custom (contact sales) and based on
  data egress beyond the free allocation.
