# Look up a barcode

> Look up published products and cigar contents by barcode.

<ParamField header="x-boxpressd-key" type="string" required>
  Your developer application key.
</ParamField>

<ParamField path="barcode" type="string" required>
  A barcode containing 6 through 32 digits. Non-digit characters are removed before lookup.
</ParamField>

```bash theme={null}
curl "https://api.boxpressd.com/v1/products/barcode/012345678901" \
  --header "x-boxpressd-key: $BOXPRESSD_DEVELOPER_API_KEY"
```

The response contains the normalized barcode and a `products` array. Each product includes `contents`; a sampler can contain zero, one, or multiple linked cigars. No published match returns `404 not_found`.
