Hi, unless you've exhausted your quota limits for the month, you should be able to view results. Can you try the following sample python code or submit your request using Postman? Let me know if you have any further questions or concerns. Thanks.
import requests
url = "https://westus.api.cognitive.microsoft.com/bing/v7.0/images/search?q='abstract art'"
headers = {
'Ocp-Apim-Subscription-Key': '<key>'
}
response = requests.request("GET", url, headers=headers)
response.json()
