5. If you want, you can also delete your account and the related API-key.

Installation

pip install fingrid-py

Usage

Fetch data using utility functions

api_key = "<your own API key>"

from fingrid import get_data, get_series_metadata

# Get datasets' metadata:
metadata_dict = get_series_metadata(api_key)                    # as json dict
metadata_df = get_series_metadata(api_key, to_dataframe=True)   # as Pandas.DataFrame

# Get datasets' timeseries data:
data_df = get_data(
  api_key,
  [277, 317, 347],
  "2025-09-01 01:00",
  "2025-09-10 01:00",
)

Call directly API endpoints

There are 9 different endpoints provided by API. All endpoints work in the same way with the same methods.
You can easily import and instantiate the endpoint's class and call the get() method to get the raw data in json format.

# Example

from fingrid import GetHealthStatus

health = GetHealthStatus(api_key).get()

Check out the parameters of each endpoint here.
Alternatively, you can call the get() method and the system will complain if any required parameter is missing.

Information for Developers

Technical API documentation for developers is available here.

• You can access data in JSON and DataFrame formats.
• Each dataset has a unique datasetId number that you need to use in API requests. Find about available datasets here.
• You can make 10,000 requests in 24h period and 10 requests per 1 minute with one API-key. Please contact the admin if you need more.
• Timestamps are by default presented in UTC time zone.
• If you request frequently updated data from an extended date range, you may receive an error message that results from exceeding the maximum allowed API payload.
