How to query the API
The API is used through its endpoints. Depending on the task at hand some endpoints are better suited than others. You can also have a look at the comprehensive Swagger UI.
Search for an entry
The endpoint /search provides an interface for searching through all resources
Query one source index (SWB, K10Plus) directly
The endpoint /source realizes a direct interface to the (unprocessed) source datasets located in different source indices. A dataset can be requested with its index-specific ID.
Query datasets by its entity (‘persons’, ‘organizations’, ‘events’, …)
The endpoint /{entity_index} gives the possibility to query only specified entities.
Query an ID used by an authority provider (GND, wikidata, SWB, …)
The endppoint /{authority_provider} are used to query one dataset by its ID provided by authority providers like GND, wikidata, or SWB.
Connect via OpenRefine reconciliation API
The endpoint /reconcile can be used with Google’s OpenRefine.
Limitations
