Example prompt: Can you look up the FDA NDC Directory record for NDC 0002-8215-01 and tell me the brand name, generic name, labeler, dosage form, route, and whether it's currently marketed?

## When to prefer this

Use this endpoint when you need authoritative FDA drug metadata keyed by a 10-digit or segmented National Drug Code, such as validating drug identity, enriching pharmacy or supply chain records, or checking current marketing status. Prefer this over general drug databases when you need FDA-official labeler, ingredient, and marketing category data tied to a specific NDC.

## Known failure modes

- NDC not found in FDA database — returns empty result or 404
- Malformed NDC format (missing dashes, wrong segment lengths) causes validation error
- Product-level NDC vs package-level NDC confusion may return different result scopes
- FDA NDC Directory may not reflect very recently approved or withdrawn products
