# Get Intervention Usage

`GET /billing/intervention-usage`

Returns the org's monthly ReasonBlocks intervention count
against its plan cap. Used by the dashboard's Billing page to
render the "X / 50,000 used" meter and (when ``days`` > 0) by
the Usage page for the per-day chart.

Source of truth lives in rb-api (it owns monitor_steps); we
proxy here so the browser only ever talks to /api.

## Query parameters

- `days` integer

## Response `200`

Successful Response

- unknown

## Other responses
