SSL API documentation
There is a way to check SSL expiration programmatically, it's called SSL API! If you want to check if a million websites have SSL certificates installed, you can do it effortlessly.
SSL API code examples
You can use our SSL API with any programming language, because requests are made through HTTPS. See code examples here.
How to use our SSL API
Using WhoAPI's SSL API is similar to using our other APIs. You make a request for a certain domain name, and we respond with the data. In SSL API, you will get information if there is an SSL certificate installed in the website, and when it expires.
SSL API use case
You can build a SSL expiration notification service, or just check the websites you own. We created such service in the past, and we also conducted research. You can check the research results in the link below.
I am always on a lookout for obscure API’s and want to get my hands on them before everybody else. Same with WhoAPI, only I used the heck out of them!
