Understanding the API Results

For search queries (such as: https://api.fda.gov/device/enforcement.json?search=classification:"Class+III"), the results section includes matching Device Enforcement reports returned by the API.

Each enforcement report consists of two major sections:

• Enforcement report data: General information about the enforcement report.
• An openfda section: An annotation with additional product identifiers, such as UPC and brand name, of the drug products listed in the enforcement report, if available.
