elpris.eu - Proxy API (Sweden)

This service mirrors Elprisetjustnu.se for Swedish zones SE1-SE4 in JSON format.

The platform targets micro-devices such as Shelly, ESP32, or similar embedded systems. The JSON output is deliberately minimal - all non-essential metadata is removed to reduce bandwidth and memory footprint, ensuring efficient parsing even on devices with limited resources.
Request policy: Usage of this service is subject to the Terms & Conditions.

The API uses the same structure as Elprisetjustnu API: .../api/v1/prices/[ÅR]/[MÅNAD]-[DAG]_[SE1–SE4].json with the base domain replaced by se.elpris.eu, and with optional query parameters for alternative formats (avg24, legacy, unit).
