# List channels for a cycler

`GET /cyclers/{cycler_id}/channels`

List channels for a cycler with pagination and filtering.

Filter parameters support Supabase filter operators:
- Text fields (name, id_text, created_by_email): use ``ilike.%value%`` for
  partial match
- Date fields: use ``gte.value``, ``lte.value``, etc.
- Date range: use created_at_gt and created_at_lt for between queries

``q`` is the free-text search box's param: it narrows on channel name substring
plus a prefix full-text match over ``search_vector``, and composes with the
column filters above.
