n3rgy Customer Service API V2
The consent-scoped smart-meter data API of the n3rgy platform. A business holding a valid n3rgy API key lists the properties (MPxNs) it has active consent for, discovers which utilities (electricity, gas) and reading types (consumption, production, tariff) are available for each, and retrieves the underlying half-hourly data. The same contract also covers meter update-frequency control, MPxN and address lookup, read-inventory / firmware and last-communications checks, on-demand "update now" fetches, push-notification configuration, and an upload/devices surface for non-DCC device data. Every operation is secured with the x-api-key header; consent-bearing operations additionally validate that an active consent exists for the HAN behind the given MPxN. A free sandbox with demonstration MPxNs mirrors the live contract on a separate host.
