Scan
Barcode → product
GTIN/EAN from a scanner resolves to the canonical drug row in one indexed read.
Drug Database
Solution · NDC & barcode lookup
NDC & Barcode to Drug API.
Scan a barcode, get a drug. Resolve a GTIN/EAN or a US NDC to the canonical product in one indexed read, across every identifier system.
GET /api/v1/drugs/lookup?system=gtin
What you get
The job, end to end
Resolve the identifier on a medication pack to a drug in one call. The barcode your scanner reads is a GTIN (or EAN); a US pack carries an NDC. Pass it to GET /api/v1/drugs/lookup?system=gtin&code=… (or system=ndc11) and get back the canonical drug row plus the exact pack that matched.
Identifier resolution is unified: GTIN, NDC, EAN, Pharmacode, PZN, CIP13, dm+d AMPP-ID and Swissmedic-No all hit the same endpoint and return the same shape. Resolve once, then read the full record to cross-walk between systems for the same product.
NDC
NDC in the same shape
system=ndc11 resolves a US National Drug Code with an identical response — only the system changes.
Identity
Cross-system identity
One product, many identifiers: resolve any one, then read the full record to map to the rest.
In code
A representative call
Pass a scanned GTIN or a US NDC to the same lookup endpoint and get back the canonical drug plus the matched pack.

}Coverage & sourcing
- Identifier systems: gtin, ndc11, pharmacode, cip13, pzn, swissmedic_no, ean, dmd_amppid.
- Alias data is data sourced from oddb, BAG-SL, FDA NDC and the national registers.
- Unknown identifiers return a clean 404 identifier_not_found — no fuzzy guesses.
- We are not affiliated with or endorsed by GS1, the FDA or the national registers.
Good to know
- · Lookups need the drugs:read scope.
- · Unknown identifiers return a clean 404 identifier_not_found — see the docs.
FAQ
Common questions
A linear barcode on a medication pack encodes a GTIN (or EAN). Pass system=gtin and the digits in code. The endpoint resolves it to the canonical drug row, with the matched pack returned alongside.
Yes. Pass system=ndc11 with an 11-digit National Drug Code. The same endpoint and the same response shape — only the identifier system changes.
gtin, ndc11, pharmacode, cip13, pzn, swissmedic_no, ean and dmd_amppid. Resolve any one to a single canonical product, then read the full record to cross-walk to the others.
