Evidence-backed facts

  1. openFDA exposes Elasticsearch-backed public datasets about drugs, devices, foods, and other FDA-regulated products through endpoint-specific JSON APIs. informative
  2. HTTPS requests can use a free API key for a higher daily allowance, while unauthenticated access is more limited and remains subject to published throttles. informative
  3. Clients must bind endpoint, search expression, count or limit, skip, and pagination behavior explicitly and must not publish an API key in a resource record. informative
  4. openFDA data can be incomplete, duplicated, delayed, or unsuitable for clinical use and does not establish causation, product safety, or individualized medical advice. informative
