List all datasets

import liberator

res = liberator.datasets()
print(res)

Liberator liberator;
var res = liberator.datasets();
Console.WriteLine(JsonDocumentToIndentedString(res));

let dataset_params = {
    schema:  false,
    details: true
};

liberator.datasets(dataset_params).then(function(results) {
    // Your code
});

Liberator liberator = new Liberator();

Object datasets_id = liberator.datasets(new HashMap<>());

for (Liberator.QueryResult res : liberator.Generate()) {
    Object data = res.GetData();
    if (data instanceof javax.json.JsonValue) {
        System.out.println((javax.json.JsonValue) data);
    }
}

print(liberator::datasets())

Liberator liberator;
auto ptr = liberator.datasets({});
auto json = *std::get_if<0>(&ptr);
if (json)
{
    rapidjson::StringBuffer buf;
    rapidjson::Writer<rapidjson::StringBuffer> writer(buf);
    json->Accept(writer);
    std::cout << buf.GetString() << std::endl;
}

Example output

{
  "Intraday": ["SSR_Forward_DSI", "Halt_Production_DSI", "SSR_Production_DSI", "News", "Twitter", "Stocktwits"],
  "Monthly": ["Joblink Ticker Mapping", "VerticalKnowledge Indeed"],
  "Market Data": ["daily_bars", "minute_bars", "nbbo", "trades", "daily_bars_adjusted"]
}

List entitled datasets only

Filter results to show only datasets matching your access permissions.

liberator.datasets(entitled=True)

var res = liberator.datasets(new Dictionary<string, dynamic>() {
    {"entitled", true}
});

Object datasets_id = liberator.datasets(new HashMap<>() {{
    put("entitled", true);
}});

print(liberator::datasets(entitled=TRUE))

liberator.datasets({{"entitled", true}});

Include schema and column details

# Schema only
liberator.datasets(schema=True)

# Schema with column details
liberator.datasets(schema=True, details=True)

var res = liberator.datasets(new Dictionary<string, dynamic>() {
    {"schema", true},
    {"details", true}
});

print(liberator::datasets(schema=TRUE, details=TRUE))

liberator.datasets({{"schema", true}, {"details", true}});
