- A sample receipt shows a $0.002 EIA inventory request, including a source label and an on-chain transaction reference.
Field notes
The catalog is divided into Prediction Markets, Health, Oil, Attention, Travel, and Wall Street, with endpoint counts shown for each collection. A displayed oil receipt includes an EIA source label, an inventory figure, a comparison with the five-year average, and a shortened transaction reference. The page also says failed requests are not charged; its claims about live data and settlement are presented by the site, not independently verified here.
