403 Error Testing API on Free Account

Can someone help? I making a test call to user/whoami endpoint: I keep getting the error below and can’t figure out why. Tried a few other endpoints and I get the same exact error

curl --request GET \
  --url https://sjc1.qualtrics.com/API/v3/whoami \
  --header 'Accept: application/json' \
  --header 'X-API-TOKEN: my-valid-api-token-from-qualtrics-app-here'

{
  "meta": {
    "requestId": "64f59b89-d55e-401b-ba48-c5a54bc2f00c",
    "httpStatus": "403 - Forbidden",
    "error": {
      "errorCode": "AuthZ_2.0",
      "errorMessage": "This user does not have access to this API endpoint."
    }
  }
}
