Understanding the API Results

For search queries (such as: https://api.fda.gov/other/nsde.json?search=package_ndc:"55700-019-60"), the results section includes matching adverse event reports returned by the API.

Each nsde result consists of these major sections:

  • Product Information:These fields relate to the product itself.
  • Marketing Information:Information about the marketing of the product.

For count queries (such as: https://api.fda.gov/other/nsde.json?count=product_type), the results section will look something like the following:
