Update - Web API

· One min read

We have updated the web APi for Cozie data retrieval. The change became necessary as the requests from some users exceeded the current payload limit of 6 MB. The example script was changed in to places:

  1. The 'shutil' module needs to be imported at the beginning
import shutil
  1. The new web API doesn't serve the data as JSON string. Instead, it is a two-step process. Firstly, a link is provided to a zipped .csv-file containing the data. Hence, the provided link needs to be called to then download the actual data.
# Download zipped CSV file with Cozie data
with requests.get(url, stream=True) as r:
with open('', 'wb') as f:
shutil.copyfileobj(r.raw, f)

# Convert zipped CSV file with Cozie to dataframe
with open('', 'rb') as f:
df = pd.read_csv(f, compression={'method': 'zip', 'archive_name': 'sample.csv'})

df = df.drop(columns=['Unnamed: 0'])

The initial call of the web API and the timezone manipulation of the dataframe remains the same, as does the resulting Pandas dataframe.
