Closient is a GS1-conformant Digital Link resolver. A GTIN can be resolved to structured product data, a consumer product information page, warranty info, recall status, and more.

​
When to use

  • The agent has a GTIN (or scanned barcode) and needs product detail.
  • The agent received a GTIN from local-product-search and wants the full product record.

​
Two ways in

GET /products/api/v1/products/{gtin}
Accept: application/json
Returns the full ProductOut schema: product_name, brand, manufacturer, image_url, description, net_content, GPC taxonomy, dimensions, weight, country_of_origin, data quality signals (confidence_score, field_confidence), ownership state (is_claimed, claim_verification_status).

​
GS1 Digital Link (consumer page or linkset)

GET /01/{gtin}
Accept: text/html            # consumer product information page
Accept: application/json     # structured JSON
Accept: application/linkset+json   # all available link types

​
Qualifier paths

  • /01/{gtin}/10/{batch} — resolve with batch/lot identifier
  • /01/{gtin}/21/{serial} — resolve with serial number
  • ?linkType=gs1:pip / gs1:warranty / gs1:recallStatus — specific link types

​
What’s NOT in the response

Certifications, allergens, and recall data live in separate APIs. Use:
  • check-recalls for recall/safety notice status
  • /certifications/api/v1/... for product certifications
  • check-recalls — active recalls for this GTIN
  • compare-products — diff two GTINs side-by-side
  • local-product-search — find where to buy this GTIN near you
