PostgREST

In addition to the DDN which lets you run arbitrary SQL queries, every dataset on Splitgraph also has a read-only OpenAPI-compatible endpoint that you can use to query it, powered by PostgREST. While less powerful, PostgREST queries are simpler to construct than SQL.

Example:

$ curl https://data.splitgraph.com/splitgraph-demo/votes_by_state/latest/-/rest/votes_by_state?state_postal=eq.DC

[{"candidate_normalized":"clinton","state_postal":"DC","total_votes":282830},
 {"candidate_normalized":"in","state_postal":"DC","total_votes":6551},
 {"candidate_normalized":"johnson","state_postal":"DC","total_votes":4906},
 {"candidate_normalized":"stein","state_postal":"DC","total_votes":4258},
 {"candidate_normalized":"trump","state_postal":"DC","total_votes":12723}]

If you're using the sgr CLI, you can also use a shorthand, sgr cloud curl, that takes care of all the scaffolding around generating the URL and making sure you're logged in:

$ sgr cloud curl splitgraph-demo/votes_by_state "votes_by_state?state_postal=eq.DC"

[{"candidate_normalized":"clinton","state_postal":"DC","total_votes":282830},
 {"candidate_normalized":"in","state_postal":"DC","total_votes":6551},
 {"candidate_normalized":"johnson","state_postal":"DC","total_votes":4906},
 {"candidate_normalized":"stein","state_postal":"DC","total_votes":4258},
 {"candidate_normalized":"trump","state_postal":"DC","total_votes":12723}]
