GS1

GS1 (GS1 AISBL) is the not-for-profit, neutral standards body headquartered at Avenue Louise 523, 1050 Brussels, Belgium, that maintains the identification keys and data standards the rest of the supply chain hangs its transactions on — GTIN, GLN, SSCC, GINC and GSIN, the barcode and EPC/RFID capture standards, EPCIS and the Core Business Vocabulary for supply chain visibility events, GS1 Digital Link, and EANCOM, GS1's own subset of UN/EDIFACT. GS1 does not run a commercial logistics service; it sits underneath every party in the chain, defining the identifiers a shipper, forwarder, carrier, terminal, customs authority and last-mile network all quote at each other. Its API posture is unusually open for a standards body: the full standards library is downloadable free as PDF from ref.gs1.org with no login, EPCIS 2.0.1 ships a normative OpenAPI 3.0.3 REST binding plus JSON Schema, XSD, WSDL, SHACL and JSON-LD ontologies, and GS1 AISBL itself operates a live, unauthenticated GS1-Conformant Resolver at id.gs1.org. What is gated is the other half — issuing GS1 identifiers and querying the Verified by GS1 registry are federated to national GS1 Member Organisations and sold under paid membership or a commercial API subscription, not offered self-serve by the Global Office.

GS1 publishes 6 APIs on the APIs.io network, including Capture API, Discovery API, Events API, and 3 more. Tagged areas include Logistics, Supply Chain, Belgium, Standards, and Track and Trace.

The GS1 catalog on APIs.io includes 1 JSON-LD context.

GS1’s developer surface includes documentation, tooling, and 20 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/gs1: open an issue to ask a question, or submit a pull request to add artifacts.

  description: GS1 AISBL's own live, unauthenticated GS1-Conformant Resolver, implementing the GS1-Conformant Resolver Standard

    owner's target resource or, on request, an RFC 9264 linkset enumerating every registered link type for that key. The resolver
    description document at /.well-known/gs1resolver declares the supported primary keys — 00 (SSCC), 01 (GTIN), 253 (GDTI),
    255 (GCN), 401 (GINC), 402 (GSIN), 414/415/417 (GLN), 8003 (GRAI), 8004 (GIAI), 8006 (ITIP), 8010 (CPID), 8013 (GMN) and
    8017/8018 (GSRN) — which includes the consignment and shipment keys logistics parties actually quote. No key, no signup
    and no contract is required to call it.
