negative.code:     + observedFrom: `2016-10-15T08:00:00Z` (string, optional) - ISO8601 timestamp notation, means incl. this timestamp; always provide a time offset, e.g. 'Z' for UTC; optional: a request may provide correct offset (so that server can convert to UTC).
      + observedUntil: `2016-10-15T09:00:00Z` (string, optional) - ISO8601 timestamp notation, means incl. this timestamp; always provide a time offset, e.g. 'Z' for UTC; optional: a request may provide correct offset (so that server can convert to UTC).
      + observedPeriod: `PT0S,PT1H,PT3H,PT12H,PT24H` (string, required) - comma separated list of periods to be retrieved. use ISO8601 time duration notation. PT0S refers to observations at a moment in time. PT1H applies one hour aggregation.
      + timeZone: `Europe/Paris` (string, optional) - Time zone refers to the IANA Time Zone Database (TZDB).
