# Query Rates

`GET /v0/inboxes/{inbox_id}/metrics/rates`

> Rolling bounce and complaint rates for the inbox. At each `period`
> grid point, the bounced (or complained) messages over the preceding
> `window` divided by the messages sent over the same window, with the
> send count alongside. Account moderation evaluates the organization-wide
> rate, so use the organization endpoint to see the number it acts on;
> the inbox view shows which inboxes contribute. Defaults to the rolling
> 24-hour rate sampled hourly over the last day; `start` must be within
> the last 90 days, `window` must be a whole multiple of `period`, and
> the range plus window divided by `period` must not exceed 1000
> buckets.

> **CLI:**
> ```bash
> agentmail inboxes metrics query-rates --inbox-id <inbox_id>
