# List statements

`GET https://evohub.io/api/v1/billing/statements`

Part of the [Billing API](https://docs.evohub.io/billing.md) reference · operationId `listStatements`.

The organization's monthly statements, newest period first, without
their lines (read one statement for those).

`total_usd` is the period's own usage; `amount_due_usd` is what the
statement actually asks for, adding amounts carried in from earlier
months that were too small to charge on their own.

Requires the `billing:invoice:read` scope.

## Authorization

Any one of:

- `bearerKey`
- `headerKey`

Where:

- `bearerKey`: HTTP Bearer — An EvoHub API key (`evohub_…`) as a bearer token.
- `headerKey`: API key in the header `X-API-Key` — An EvoHub API key (`evohub_…`).

## Query parameters

- `limit` (integer, default `24`, min 1, max 100): How many statements, 1–100. Any other value means 24.
