em6 has just released a new API that returns prices for the last 24 hours (48 trading periods) for these six nodes only: OTA2201, WKM2201, KIK2201, ISL2201 and BEN2201.
The new API can be reached at: https://api.em6.co.nz/ords/em6/data_api/price/free_24hrs/ and does not require any authentication to access. This replaces a previous price API (https://api.em6.co.nz/ords/em6/data_api/price/24hrs/) which, from Tuesday 27 January 2026 can only be accessed if you have Basic or Price subscriptions.
For more details on our APIs, including other free-to-air services, please check our API Integration Guide or contact us for a free trial at call@ems.co.nz.
