# Query meter

`POST /openmeter/meters/{meterId}/query`

Query a meter for usage.

Set `Accept: application/json` (the default) to get a structured JSON response.
Set `Accept: text/csv` to download the same data as a CSV file suitable for
spreadsheets. The CSV columns, in order, are:

`from, to, [subject,] [customer_id, customer_key, customer_name,] <dimensions...>, value`

The `subject` column is emitted only when `subject` is in the query's
`group_by_dimensions`. The three `customer_*` columns are emitted together only
when `customer_id` is in the query's `group_by_dimensions`.

## Path parameters

- `meterId` string, required — ULID (Universally Unique Lexicographically Sortable Identifier).

## Request body

- MeterQueryRequest — A meter query request.
  - `from` string, date-time — [RFC3339](https://tools.ietf.org/html/rfc3339) formatted date-time string in UTC.
  - `to` string, date-time — [RFC3339](https://tools.ietf.org/html/rfc3339) formatted date-time string in UTC.
  - `granularity` 'PT1M' | 'PT1H' | 'P1D' | 'P1M' — The granularity of the time grouping. Time durations are specified in ISO 8601 format.
  - `time_zone` string — The value is the name of the time zone as defined in the IANA Time Zone Database (http://www.iana.org/time-zones). The time zone is used to determine the start and end of the time buckets. If not specified, the UTC timezone will be used.
  - `group_by_dimensions` string[] — The dimensions to group the results by.
  - `filters` MeterQueryFilters — Filters to apply to a meter query.
    - `dimensions` object — Filters to apply to the dimensions of the query. For `subject` and `customer_id` only equals ("eq", "in") comparisons are supported.
