# List parameterized models for a cell specification or project

> List parameterized models with pagination, scoped by cell spec or project.

Provide exactly one scope:

- ``cell_spec_id`` lists models for a single cell specification. This is the
  path parameter when called via ``/cells/{cell_spec_id}/parameterized_models``.
- ``project_id`` lists models across every cell specification linked to the
  project. ``cell_spec_id`` may additionally be passed to narrow a
  project-scoped query to one cell specification.

Parameters
----------
cell_spec_id : str | None
    Cell specification to scope to. Required when ``project_id`` is not given.
project_id : str | None
    Project to scope to. When set, ``cell_spec_id`` is an optional further
    filter rather than the primary scope.
limit : int
    Maximum number of models to return per page (1-1000). Defaults to 100.
    The upper bound is 1000 so callers (e.g. the optimization clone form)
    can load every model for a project in one request.
offset : int
    Number of models to skip for pagination. Defaults to 0.
