About the API:
This API provides information about the SSL certificates that are present in a given website.
Pass the URL to lookup, and receive the location of the SSL provider and the validity of that certificate as well.
Be able to look up programmatically the validity of the SSL certificates of the pages you want to check. This API is ideal for those security companies that want to know if the website is safe for their users and if they have the necessary certificates to operate.
Besides API call limitations per month, there is a limitation of 5 requests per second.

But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
You can monitor your API usage through the response headers included with every request:
x-zyla-api-calls-monthly-used: Shows the total number of API requests you have used during the current billing period.
x-zyla-api-calls-monthly-remaining: Shows the number of API requests you have remaining for the current billing period.
Yes, you can cancel your subscription at any time. Simply go to the Pricing section of the API you're subscribed to and click the "Unsubscribe" button.
