# Resolve GTIN

> Resolve a GTIN (8/12/13/14-digit product barcode) via GS1 Digital Link to structured product information.

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

### REST (recommended for agents)

```
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

## Related skills
