summary: List reporting metadata
description: 'Returns tables, columns and help text available to the advertiser (same `key` and `format` query parameters as **GET /apidata**).
The response shape depends on `format`: `json` returns a structured JSON object, while `csv`, `excel`, and `human` return tabular text/binary representations of the same metadata.
There is **no** `filter` query parameter on this route; call **`/apidata`** to apply **`filter`**. Use **`/apilist`** first to discover column identifiers for `data`, `sum`, and `filter`.'
