Steps
Authenticate with your EIA API key as described in the API key/query-mechanics route.
Query the petroleum/pri/wfr route to confirm the residential propane series is available.
Request /data on that route with frequency=weekly and a data[] column for the price value.
Filter to the national aggregate (rather than a PADD or state facet) to get the U.S. average residential propane price.
Parse the returned time series for the price values and period timestamps.
Known gotchas
EIA only publishes weekly residential/wholesale heating oil and propane prices during the heating season (October through March); expect no new weekly data points outside that window.
Confirm you're reading the residential series and not the wholesale series — both exist under the same wfr route family with different facet/series identifiers.
Prices are reported in dollars per gallon; verify units before feeding the value into downstream pricing logic.
