This endpoint returns information about licensing. See license autoloading for additional background.
In the response:
autoloading_used will be true if an autoloaded license was provided to the
node, false otherwise. This should always be true from Vault 1.11.0 onward.
autoloaded is the autoloaded license if autoloading_used is true.
persisted_autoload is the autoloaded license the active node last wrote to
storage; this is only used to detect inconsistently licensed nodes in the
cluster. It cannot be used as a license itself.
stored was used for the stored license prior to Vault 1.11.0. Stored licenses are no longer supported.
autoloaded, and persisted_autoload will both have the same structure.
