# Wikipedia Category Members API

Members of a category with sort keys, timestamps and the category counts.

`GET /v1/wikipedia/categories/Category%3ALiving%20people/members?lang=en` returns `data.members`, one row per member. Each row has `pageId`, `ns`, `title`, `sortKeyPrefix`, `type` and `timestamp`. `type` is `page`, `subcat` or `file`, and `timestamp` is when the member joined the category.

`data.category` holds `size`, `pages`, `files`, `subcats` and `hidden` when the counts are available. `data.complete` is false when the counts are temporarily unavailable, while `members` is still the full page. Set `type=page`, `subcat` or `file` to narrow the members. `sort` is `sortkey` (the default) or `timestamp`.

Pass the title with its `Category:` prefix. `limit` accepts 1 to 500 and `cursor` continues with `data.page.nextCursor`. A category that exists with no members is `found` with `empty: true`; a category that does not exist is `not_found`.

## FAQ

### Do I include the Category prefix?

Yes. Pass Category:Living people as the title, URL-encoded in the path. A bare Living people is a different title and may be not_found.

### Why is complete false?

The member list is still complete for the page, but the category counts are temporarily unavailable. category may then be null. The rows in members are unaffected.

### Can I walk a whole category?

Yes. Follow data.page.nextCursor while data.page.hasMore is true. Each page is a separate request. Use type to include or skip subcategories and files.

### How is category paging billed?

Pricing is documented on the operation in the API registry (shown on this page). Confirm on every response with meta.creditsCharged: that field is the billing source of truth. Each paginated page is a separate billed request.
