# Pagination

List operations return `items` in the documented stable order plus `page.next_cursor`; pass it back as `cursor` with the same filters (a `valid_at`/`known_at` you did not supply may keep defaulting to the request time between pages). Cursors are opaque, signed by the server and expire; a malformed, edited, forged or expired cursor is a `400 invalid-request` naming `cursor`. `limit` is bounded per operation.
