Routing

Get the per-leg fee model for an approved cross-venue market link

Returns the fee model each leg of the link charges per side, so a client can show the routing cost before quoting a size. Every union leg is listed; executable says whether the router fires on it for THIS caller and connectable whether connecting a Kalshi account would make it so. An unrecognized link is a 200 with routed: false and an empty legs. Auth & scope. Requires trade:read for provider.
