# List Usage for Month

> Get detailed usage charges for a specific calendar month

Get a paginated list of **posted usage charges** for a specific calendar month. This is a convenience endpoint equivalent to [List Usage](/api-reference/billing/usage) with a `from`/`to` date range scoped to one month.

Use this when building monthly reports or billing dashboards.

### Headers

<ParamField header="Authorization" type="string" required>
  API key or Cognito JWT: `Bearer sk-xxxxxx`
</ParamField>

### Query Parameters

<ParamField query="year" type="integer" required>
  Four-digit year (for example, `2026`).
</ParamField>

<ParamField query="month" type="integer" required>
  Month number from 1 to 12.
</ParamField>

<ParamField query="limit" type="integer" default="50">
  Maximum number of items to return (minimum 1).
</ParamField>

<ParamField query="offset" type="integer" default="0">
  Number of items to skip for pagination.
</ParamField>

### Response

Same shape as [List Usage](/api-reference/billing/usage): a paginated `UsageListResponse` with `items`, `total`, `limit`, `offset`, and `has_more`.

<RequestExample>
  ```bash cURL theme={null}
  curl "https://api.mor.org/api/v1/billing/usage/month?year=2026&month=5&limit=20" \
    -H "Authorization: Bearer sk-your-api-key"
  ```
</RequestExample>

<ResponseExample>
  ```json Success theme={null}
  {
    "items": [
      {
        "id": "0192a1b2-c3d4-7890-abcd-ef1234567890",
        "created_at": "2026-05-15T09:12:00Z",

        "amount_paid": "0.00",
        "amount_staking": "0.0088",
        "amount_total": "0.0088"
      }
    ],
    "total": 42,
    "limit": 20,
    "offset": 0,
    "has_more": true
  }
  ```
</ResponseExample>

<Note>
  For arbitrary date ranges, use [List Usage](/api-reference/billing/usage) with `from` and `to` query parameters instead.
