# ASIN to GTIN Results

When making a request with the  `type`  parameter set to  `type=asin_to_gtin`  Rainforest API will attempt to look up GTIN / EAN / UPC / ISBN numbers for the ASIN and Amazon domain specified in the  `asin`  and  `amazon_domain`  parameters.

:::hint{type="info"}
GTIN / EAN / UPC / ISBN values are retrieved from public domain sources (as they are not published by Amazon themselves). If we are not able to find the GTIN will we return a 404 status.
:::

An example of the JSON object returned from an ASIN to GTIN request is shown below:

```json
{
  "request_info": {
    "success": true,
    "credits_used": 1,
    "credits_remaining": 999
  },
