## Get TLD Performance Summary

**get** `/radar/tlds/performance/summary/{dimension}`

Returns a summary of TLD authoritative nameserver performance grouped by the specified dimension.

### Path Parameters

- `dimension: "LATENCY" or "NAMESERVER_LATENCY" or "LOCATION_LATENCY"`

  Dimension to summarize TLD nameserver latency by.

  - `"LATENCY"`

  - `"NAMESERVER_LATENCY"`

  - `"LOCATION_LATENCY"`

### Query Parameters

- `continent: optional array of string`

  Filters results by continent. Specify a comma-separated list of alpha-2 codes. Prefix with `-` to exclude continents from results. For example, `-EU,NA` excludes results from EU, but includes results from NA.

- `dateEnd: optional array of string`

  End of the date range (inclusive). Alternative to `dateRange`; provide together with `dateStart`. When requesting comparison series, every series must resolve to the same duration as the main series. Each `dateStart`/`dateEnd` is floored to the nearest 15 minutes before evaluation, so windows whose durations match only before alignment may be rejected.

- `dateRange: optional array of string`

  Filters results by relative date range ending at the current time, with each value producing a separate series. Use `<n>d` for days (up to `364d`) or `<n>w` for weeks (up to `52w`). Append `control` to request the equivalent previous period for comparison: the comparison window is shifted back by the current window's length rounded up to a whole number of weeks, so it keeps the same weekday alignment and does not overlap the current window (e.g. `7dcontrol` covers days -14 to -7, `10dcontrol` covers days -24 to -14). For example, pass `7d` and `7dcontrol` to compare this week with the previous week. All series must resolve to the same duration as the main series; relative ranges (including `control`) satisfy this automatically. Use this parameter or set specific start and end dates (`dateStart` and `dateEnd` parameters).

- `dateStart: optional array of string`

  Start of the date range. Alternative to `dateRange`; provide together with `dateEnd`. When requesting comparison series, every series must resolve to the same duration as the main series. Each `dateStart`/`dateEnd` is floored to the nearest 15 minutes before evaluation, so windows whose durations match only before alignment may be rejected.

- `format: optional "JSON" or "CSV"`

  Format in which results will be returned.

  - `"JSON"`

  - `"CSV"`

- `limitPerGroup: optional number`

  Limits the number of objects per group to the top items within the specified time range. When item count exceeds the limit, extra items appear grouped under an "other" category. Only supported on high-cardinality dimensions; otherwise the request is rejected. Minimum value is 2.

- `location: optional array of string`

  Filters results by location. Specify a comma-separated list of alpha-2 codes. Prefix with `-` to exclude locations from results. For example, `-US,PT` excludes results from the US, but includes results from PT.

- `name: optional array of string`

  Array of names used to label the series in the response.

- `nameserver: optional string`

  Filters results by nameserver hostname.

- `tld: optional array of string`

  Filters results by top-level domain.
