Read-only: A read that takes its filters in the body. Changes nothing, and ignores Idempotency-Key.

Searches units of measure. The filters are the exact code and when the unit of measure last changed.

## Parameters

| Name | In | Type | Required | Description |
| --- | --- | --- | --- | --- |
| `Api-Version` | header | string · v1 | yes | The API version this request targets, named by its public identifier. Required on every request; omitting it, or naming a version this company does not have, is answered with 400. This document describes version `v1`. |

## Request body

Required, `application/json`: searchUnitOfMeasuresInput.

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| `filters` | object | yes | The filters to apply. A unit of measure must match every filter you send. Send an empty object to return all units of measure. Example: `{"unitCode":"KG"}`. |
| `filters.unitCode` | string | no | Limits results to the unit of measure with this code. The match is exact. Codes are unique, so this matches at most one unit of measure. |
| `filters.modifiedSince` | date-time | no | Limits results to units of measure changed on or after this time. Format YYYY-MM-DDTHH:mm:ss.sssZ. |
| `page` | object | no | The pagination controls. Omit for the first page. Example: `{"size":50}`. |
| `page.cursor` | string | no | The cursor from the previous response's pagination.nextCursor. Omit for the first page. |
| `page.size` | number | no | The number of units of measure per page. Defaults to 50. A value above 200 is treated as 200, not rejected. |

  "filters": {
    "unitCode": "KG"
