# List Attributes

`GET /api/v1/schema/attributes`

## Request

- Base URL: `https://app.goodleads.club` (the document declares no server; this is the origin it was published from)
- URL: `https://app.goodleads.club/api/v1/schema/attributes`
- Auth: none declared

List all filterable attributes with metadata.

Each field carries its label, type, the ENFORCED operator set, `sortable`,
`masked` (anonymous callers see a redacted value), and `allowed_values`
where the vocabulary is enumerable. The default response is the bare list
every existing consumer iterates; `?include=grammar` returns
{attributes, grammar} for agents that compose queries.

## Query parameters

- `include` string, nullable: `grammar` wraps the list as {attributes, grammar} — the grammar object describes the leaf shape, and/or/not groups, set predicates, operators per type, and sort keys.

## Response `200`

Successful Response

- unknown

## Other responses

- `422`: Validation Error
