List Files

List the authenticated user's uploaded files in the request's workspace.

workspace_id narrows a master-key listing to one workspace; a keyed request is already confined to its key's own and cannot widen or move it.

Each flavor pages with its own cursor. OpenAI's after names the last file of the previous page, and has_more says whether to ask again. Anthropic's next_page is passed back as page, and ids[] reads up to 100 named files in one page. A cursor whose file has since been deleted or has expired is still a position. An after the caller never owned is a 404, and a page token this gateway did not issue is a 400.
