Check whether a PCB version is ready to be quoted and manufactured at a given quantity.

The response lists observations (problems, warnings, and notes about the design) and the
available actions that remain possible given those observations. This is the same check
the MacroFab platform uses on the PCB's Quote page.

To check whether a PCB can be instantly quoted and ordered online, look for auto_quote in
available_actions. If it is missing, the observations whose prevents_actions include
auto_quote explain why.

Approved Vendor Lists and part selection

Each line of the bill of materials is sourced through its approved vendor list (AVL); see the
Approved Vendor List endpoints. For turnkey and customer parts, a BOM line counts as
selected when its AVL contains at least one part. For consignment and inventory parts, the
check also requires the BOM line's deprecated selected_part field. Lines that have no part to
source are reported by the unselected_parts observation.

By default each BOM line is checked with the origin stored on the BOM. To check the PCB as if
some lines were sourced differently, use the POST form of this endpoint and pass part_origins.
