import accern_data
# Create a data client.
client = accern_data.create_data_client("https://api.example.com/", "SomeRandomToken")
# Set a data format/mode in which the data has to be downloaded.
# Split dates lets you divide files on the basis of dates.
client.set_mode(mode="csv", split_dates=True)  # Other modes: {"df", "json"}

Set filters:

client.set_filters({
    "provider_id": 5,
    "entity_name": "Hurco Companies, Inc.",
    "event": "Governance - Product Development, R&D and Innovation",
    "entity_ticker": "HURC",
    "entity_accern_id": "BBG000BLLFK1",
})

Set parameters to the download function:

client.download_range(
    start_date="2022-01-03",
    output_path=".",
    output_pattern="data",
    end_date="2022-03-04")

Note: To download single day's data, set end_date=None or can leave that unset:

client.download_range(
    start_date="2022-01-03",
    output_path=".",
    output_pattern="data",
    end_date=None)

OR

client.download_range(
    start_date="2022-01-03",
    output_path=".",
    output_pattern="data")

One-liner download:

accern_data.create_data_client("https://api.example.com/", "SomeRandomToken").download_range(start_date="2022-01-03", output_path=".", output_pattern="data", end_date="2022-03-04", mode="csv", filters={"entity_ticker": "HURC"})

Getting data using iterator:

for res in client.iterate_range(
        start_date="2022-01-03",
        end_date="2022-03-04"):
    do_something(res)

Error logging:

While downloading the data any critical error will get raised. Any non-critical errors, such as API timeouts, get silenced and API calls are repeated. To see a list of the last n errors use:

client.get_last_silenced_errors()
