curl --request GET --header "Authorization: Bearer YOUR\_API\_KEY" --header "Content-Type: application/json" --url "https://api.ahrefs.com/v3/site-explorer/domain-rating?date=2023-03-22&protocol=https&target=www.contractsspecialist.com.au%2Farticles%2Fhia-progress-payment-schedule-nsw%2F"
 It seems like you've provided a `curl` command to make a GET request to the Ahrefs Site Explorer API. This command will retrieve the Domain Rating (DR) for a specific URL with some headers included. However, I don't see an actual API key in the command. You should replace `YOUR_API_KEY` with your actual Ahrefs API key.

Here's the corrected `curl` command:

```bash
curl --request GET \
  --header "Authorization: Bearer YOUR_API_KEY" \
  --header "Content-Type: application/json" \
  --url "https://api.ahrefs.com/v3/site-explorer/domain-rating?date=2023-03-22&protocol=https&target=www.contractsspecialist.com.au%2Farticles%2Fhia-progress-payment-schedule-nsw%2F"
```

Replace `YOUR_API_KEY` with your actual Ahrefs API key to get the desired output. The command will return a JSON response containing the Domain Rating (DR) and other related information for the specified URL.

Keep in mind that the provided date (2023-03-22) is in the past, and
{"domain_rating": 57.5}
