    Every Barchart OnDemand request carries an `apikey` query parameter (for
    example `?apikey=YOUR_API_KEY`). Keys are issued with a Barchart OnDemand
    subscription or enterprise agreement; a limited free trial key is available
    for evaluation. Real-time exchange data additionally requires exchange
    licensing.
