Example using curl://

Send the /epw/<dataset_name> command using curl:

curl -b cookies https://api.ensims.com/jess_web/api/epw/ISL_AL_Hornafjordur.AP.040820_TMYx

On success, the contents of the EPW file will be returned. If the specified dataset is not found, an HTTP 404 Not Found error will be returned.

Example using Python Requests

Make sure Requests is correctly installed in your Python environment, and run the following lines:

import requests

# Security is not required
r = requests.get('https://api.ensims.com/jess_web/api/epw/ISL_AL_Hornafjordur.AP.040820_TMYx')

# Show returned object  
r.json()
