Steps
Construct a request against a route such as natural-gas/pri/fut/data/ (or the analogous petroleum route) including the required frequency and facets parameters
Set frequency to match a periodicity actually offered by that route, e.g. daily or monthly
Use facets (e.g. commodity/series-specific facet keys) to filter down to the exact series needed
Query facet values themselves via the API to discover valid facet options before filtering
Paginate if needed, since the API will not return more than 5,000 rows in a single response, with the total row count reported in the response
Known gotchas
Exceeding the 5,000-row response cap silently truncates results; check the reported total row count and paginate
frequency must match a periodicity actually offered by that specific route/series or the request fails
Route structure and required facet keys differ across domains (electricity vs petroleum vs natural gas), so a working query for one route cannot be copy-pasted to another without adjusting facets
