List the postal codes and cities Vwala can price

Returns every Serviceable Location — each (postal code, city) pair Vwala can price — with the energy types available there. Use it to populate a postal-code/city picker, to validate a location before calling comparison or simulation, and to round-trip the city value straight into those endpoints' supply-point inputs. provides lists the priceable energy types: ELECTRICITY is present for every location, GAS only where a supported gas distribution operator exists — so a location whose provides omits GAS is exactly one for which a gas comparison/simulation would return supply-point/gas-not-available. Pass postalCode to narrow to a single code; several cities can share one code, so the result may hold more than one location. Coverage currently spans the Fluvius/Flanders distribution network; a location absent from this list is not serviceable and pricing it returns supply-point/location-not-serviceable.
