The SMW API is a web service API enabling external components or data services to access the Semantic MediaWiki database using a standardized HTTP request.

Content provider

SMW API service is being provided by the API modules interface which extends the MediaWiki API to gain access to serialized query results.

Content consumer

Momentarily (Semantic MediaWiki 1.9.0) two result printers (Event calendar, Datatables) are content consumers and use the query result serialization provided by the SMW API.
