Yes, you just purchase your electricity with a market price contract (usually with added margin) and every day the next day prices are published around 3pm Finnish time (perhaps 12 UTC). Then just use the free APIs to load data and use the data to adjust when you spend electricity on what. E.g. to charge EV on cheapest hours, or load batteries, or when you fire up your electric Sauna...
These days the price is different for every hour, in near future they move to 1/4 hour pricing.
About 10% of finnish household contracts are market price contracts. Most of the contracts are kinda continuous (price changes every 12 months) or fixed (e.g. a two year fixed price contract).
