first run SPARQL Anything (https://github.com/SPARQL-Anything/sparql.anything) as a 
service then you can invoke a SPARQL query as demonstrated below.

you can also run SPARQL Anything not as a service but 1 query at a time  
e.g.  `java -jar sparql-anything.jar --query some.rq`



curl --silent 'http://localhost:3000/sparql.anything'  \
--header "Accept: text/csv" \
--data-urlencode 'query=
PREFIX  xyz:  <http://sparql.xyz/facade-x/data/>
PREFIX  xsd:  <http://www.w3.org/2001/XMLSchema#>
PREFIX  skos: <http://www.w3.org/2004/02/skos/core#>
PREFIX  fx:   <http://sparql.xyz/facade-x/ns/>
PREFIX  ex:   <http://example.com/>
CONSTRUCT
  { 
    ?s ?p ?o .
  }
WHERE
  { SERVICE <x-sparql-anything:>
      { fx:properties
                  fx:location    "https://api.github.com/repos/phantomics/april/issues?state=all&per_page=100&page=1" ;
                  fx:media-type  "application/json" .
        ?s        ?p             ?o
      }
  }
'


which produces:

@prefix ex:   <http://example.com/> .
@prefix fx:   <http://sparql.xyz/facade-x/ns/> .
@prefix skos: <http://www.w3.org/2004/02/skos/core#> .
@prefix xsd:  <http://www.w3.org/2001/XMLSchema#> .
