description: >-
  DBpedia is a community open-source project; all public API services (SPARQL endpoint, Lookup,
  Spotlight, Live, Linked Data, and Databus) are provided free of charge under open data
  principles. No commercial plans or paid tiers are offered. Self-hosted deployment options
  are available for all major services via Docker. The project is sustained by community
  contributions, academic partnerships, and sponsorships from InfAI and others.
notes: >-
  Fair-use policies apply to the public SPARQL endpoint (10,000 row limit, 120-second timeout,
  50 parallel connections, 100 req/sec per IP). Heavy users are encouraged to download datasets
  from Databus or run local Virtuoso instances.
