Energi Data Service (Energinet, Denmark) API

Energinet's Energi Data Service serves Danish electricity and gas system data — CO2 intensity, production declarations and more — through a keyless JSON REST API. The terms page says: "Data published on Energi Data Service is subject to the conditions of Creative Commons CC-BY 4.0. Users may copy, change and distribute data freely, even for commercial purposes."

Coverage

Datasets such as CO2Emis (5-minute CO2 intensity by price area DK1/DK2) and DeclarationProduction, queryable with start/end/columns/filter/sort/offset/limit parameters and downloadable as JSON, CSV or Excel. Update cadence: dataset-specific. On selected datasets, request-frequency guidance is included in the description.

Verdict

Danish electricity and gas system data (5-minute CO2 intensity, production declarations and other datasets by price area) from the national TSO via a keyless JSON API. Licensed CC BY 4.0: "Data published on Energi Data Service is subject to the conditions of Creative Commons CC-BY 4.0. Users may copy, change and distribute data freely, even for commercial purposes." Conditions: "Users must give appropriate credit and indicate if data has been changed." Rate limits: "Energi Data Service applies dataset‑specific (differentiated) rate limits to API usage." Exceeding a limit returns HTTP 429 with the message "Rate limit is exceeded. Try again in X seconds". Signal Lab's note: Energinet separately says it stores each caller's IP address for 3 months for usage statistics (a privacy note, not a data restriction).
