If you’re completely new to Clarity Grid APIs, this quickstart guide is the perfect starting point. It covers the essentials of acquiring credentials, submitting a request, and retrieving data. Let’s dive in and get started.

To get started with using these APIs, please follow these steps:

To ensure privacy and authentication of every request to Clarity Grid APIs, it’s crucial to create a User Account. This will enable us to identify who is making the call and keep your data confidential.

After contacting us to request your account, you can expect to receive an email containing your contract information. Once you have reviewed and submitted your contract, we will provide you with your API Key and technical support contacts so you can get started.

Try out the API Live Demo

The API live demo page provides detailed information on the API endpoints, query parameters, payload and response format, and error handling. You can access the API demo by visiting Api.Claritygrid.net 

Once you’ve read the API documentation, you can begin by authenticating your session by sending your unique UUID to our login endpoint using a post request (https://map.claritygrid.net/ecservice/login). Once you have the cookie returned from the API, you will be able to make subsequent requests to the API. The parameters for our login endpoint are as follows:


Field Name

Data Type





Unique API key provided by Clarity Grid upon signing up for API access.

uu_id“: “yourapikeyhere”,



Determines what app group the user is logging in as.



Sample Payload

Below is a sample payload required by this endpoint.


uu_id“: “yourapikeyhere”,



Sample Python Code

Below is a sample of Python code that can be used to authenticate using the requests and simplejson Python Libraries.

# Tariff api sample cli using python requests library

# For help : jdieter@claritygrid.net

# You will need some python libs installed to run this

#    pip3 install requests

#    pip3 install simplejson



import requests

import simplejson as json


host = ‘https://map.claritygrid.net’


#login to get session (authcookie) using your api secret

url = host + ‘/ecservice/login’ 

postbody = {“uu_id”:”yourApiSecretGoesHere”,”app_group”:”API”}

header = {“content-type”: “application/json”}

response = requests.post(url,data=json.dumps(postbody),headers=header, verify=True)




# *Note – ISO values are: 1-NEISO, 2-NYISO, 3-PJM, 4-MISO, 5-CAISO, 6-SPP, 7-ERCOT, 8-SERC, 9-WECC

url = host + ‘/ecservice/api/distributors?operator_id=5’ 

header = {“content-type”: “application/json”} 

response = requests.get(url,headers=header, verify=True, cookies=authcookie)

# the next line will fail with a 401 if the auth failed


rsp_json = response.json()

# Print all distributors

for dist in rsp_json:



Once you’ve read the API documentation, you can make your first request.

We hope that these APIs will help you build innovative energy apps and products that promote energy cost transparency and savings optimization.
