Each service call is validated with a key. To validate the API call, you must add the x-api-key
header to your requests, containing your own API key. A full example using curl would look like this:
curl -X 'POST' \
'https://api.calculators.cxn.io/rest-v1/calculator/calculate/elemental-analysis' \
-H 'accept: application/json' \
-H 'Content-Type: application/json' \
-H 'x-api-key: YOUR_API_KEY' \
-d '{
"structure": "NC(CC1=CC=CC=C1)C(O)=O"
}'
In case you need a new API key, you have to unsubscribe from this product on AWS Marketplace page and subscribe again. This process will remove your previous API key associated to you account and assign a new one.
No, you can have only a single API key associated to your AWS account.
Subscribing and unsubscribing to the service is free of charge. We will bill you only for the API calls you make. Each chemical calculation has a different price based on how complex it is. For the detailed list click here.
