Input cells (25)

Paths are relative to the request’s inputs object; [] marks an array element.

Required says when a cell must be present. Always means every request needs it: the default boundary rejects the call when the cell is omitted or null. Strict means only a request that sends this target’s payloadContract selector needs it. See Run computations for the default boundary.

These cells are everything this target accepts. A member that is not published here, or is sent with the wrong JSON type, fails the call with a 400 naming each failing cell.
