The OpenFDA API has a label endpoint, which pulls in a ton of API info that DailyMed does not provide, but the info is coming from DailyMed SPLs. Example with Revlimid: https://api.fda.gov/drug/label.json?search=openfda.spl_set_id:5fa97bf5-28a2-48f1-8955-f56012d296be+AND+openfda.product_ndc:59572-402
These are the fields you can search and which it returns: https://open.fda.gov/apis/drug/label/searchable-fields
