Searches the company's active product catalog for products to add to an estimate. Each product carries the unit_price it would be added at, priced from its current cost for the property's service area plus the company's margin. On the first page, alternates lists the products the estimate's kit offers as swaps for items already on it.

Results are paginated (25 per page by default, up to 100), and filter_options lists the category, type and variant values you can filter by. Add the products you choose with POST /estimates/{id}/add_line_items.

The token's role must be allowed to edit this estimate.
