# Get a monitor's uptime

`GET https://evohub.io/api/v1/monitors/{id}/uptime`

Part of the [Uptime API](https://docs-dev.evohub.io/uptime.md) reference · operationId `getMonitorUptime`.

The share of the monitor's checks over the last `days` days that
were up, as a percentage rounded to two decimals. A degraded check
counts as up. With no checks in the range the answer is `100`; use
the per-day endpoint to tell "no data" apart.

Requires the `uptime:monitor:read` scope.
