SPARQL interface

The platform supports data access via the standard SPARQL 1.1. Protocol . The API only accepts SPARQL SELECT, ASK and CONSTRUCT queries and does not support SPARQL update queries.
One can use the

HTTP GET operation with the SPARQL query URL encoded in the query parameter query or a
HTTP POST request if the SPARQL query is large (which could exceed the maximum length of a URL)

Below is an example request with the following SPARQL query:

SELECT *
WHERE{
  ?s ?p ?o .
} LIMIT 10

The respective API calls ask for the results in the SPARQL JSON format.

GET

curl 'https://proxy.opendatagermany.io/api/ts/v1/kg/sparql?query=SELECT%20*%20WHERE%20%7B%20%3Fs%20%3Fp%20%3Fo%20.%7D%20LIMIT%2010' \
-H 'accept: application/sparql-results+json' \
-H 'x-api-key: <APIKEY>'

POST

curl 'https://proxy.opendatagermany.io/api/ts/v1/kg/sparql' \
-H 'accept: application/sparql-results+json' \
-H 'content-type: text/plain' \
-H 'x-api-key: <APIKEY>' \
--data 'SELECT * WHERE { ?s ?p ?o .} LIMIT 10'
