# Read the label lists of one list version

> Every value a landing page label can take in this list version, with its name and definition: the rows a write is checked against. A list can be read before StefanBrain activates it. A free read: no rate limit and no billing. Requires the `tools` scope and the account's own landing_page_label_writer grant.
