Hello everybody, I am trying to follow the tutorial on creating a http api source from the echangerate api, but apparently the api is requiring an access api key. When I try to call https://api.exchangeratesapi.io/latest?base=USD I got the reponse:

{
  "success": false,
  "error": {
    "code": 101,
    "type": "missing_access_key",
    "info": "You have not supplied an API Access Key. [Required format: access_key=YOUR_ACCESS_KEY]"
  }
}

I didn't find in the toturial any information about the access_key for this API, how this could be?
