With Cradle of War the cost of an Ansiblex jump is no longer flat. It is the base value of your ship class multiplied by the zone of the system where the jump ends, and the zone depends on how far that system is, in a straight line, from the capital system of the alliance that owns the gate.
The Ansiblex zones calculator on Capsuleers.app takes any destination system, finds the alliance that holds its sovereignty from ESI, reads that alliance's capital and returns the zone, the multiplier, the distance in light years and the cost in TJ for the ship class you pick. It also shows how many jumps a full 1,250 TJ capacitor gives and how long one jump takes to recharge.
Paste a list of systems to see how a whole network splits across the five zones, or list every sovereignty system of an alliance grouped by zone. The same zones are available as a layer on the live map. Works without login.
