countread-onlyopenFDA's most valuable feature: aggregate over any dataset by a field to get a top-terms histogram (returns `results: [{term, count}]` instead of records). Use the '.exact' field suffix to count whole phrases. Example: endpoint 'drug/event', field 'patient.reaction.reactionmeddrapt.exact', search 'patient.drug.medicinalproduct:"aspirin"' → the most common reactions reported for aspirin.
openfda_queryread-onlyGeneric escape hatch to query ANY supported openFDA endpoint with the full parameter set — covers the less-common datasets (device/pma, device/registrationlisting, device/udi, device/covid19serology, drug/orangebook, other/nsde, other/substance, tobacco/problem, etc.). Use the named search tools for the common datasets; use this for everything else or for advanced queries. openFDA REST API.
