Query EIA for state-level residential propane price series

Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗
Steps
Authenticate with your EIA API key.
Query the petroleum/pri/wfr route's metadata (without /data) to see the available facets, including a state/PADD-district facet.
Query the facet's values endpoint to get the list of valid state or PADD-district codes.
Request /data on the route with a facets[...] parameter set to your target state or PADD district.
Set frequency=weekly (or the route's documented default) and specify the price data[] column.
Known gotchas
Not every state publishes its own weekly propane series — lower-volume states may only be represented at the PADD-district level, not individually.
Like the national series, state-level weekly heating oil/propane prices are only collected during the October-March heating season.
Facet codes (state/PADD identifiers) must match exactly what the facet-values query returns; a guessed code silently returns zero rows rather than an error.
