API description

About the API:

The SSL Certificate Validation API is a tool that provides comprehensive information on the SSL certificate used by a host. SSL certificates are a crucial aspect of online security, and they provide a way for websites to establish secure connections with their visitors. The SSL Certificate Validation API allows users to quickly and easily obtain detailed information about the SSL certificate being used by a particular host.

The API provides a wealth of information about the SSL certificate, including its expiration date, issuer, public key algorithm, signature algorithm, and more. This information can be useful for a variety of purposes, such as ensuring that the SSL certificate is valid and up to date, verifying the identity of the website owner, and detecting potential security vulnerabilities.

Using the SSL Certificate Validation API is simple and straightforward. Users can make an API request by specifying the hostname or IP address of the server they wish to query. The API then returns a JSON response containing detailed information about the SSL certificate.

One of the key benefits of the SSL Certificate Validation API is that it allows users to easily monitor the SSL certificates used by their own websites, as well as those used by third-party sites they interact with. By regularly checking the SSL certificates being used by these sites, users can ensure that they are using valid and up-to-date certificates, and they can detect any potential security issues that may arise.

Another potential use case for the SSL Certificate Validation API is in developing security tools and services. Security researchers, software developers, and other professionals can use the API to build applications and services that analyze SSL certificates and detect potential vulnerabilities and threats.

Overall, the SSL Certificate Validation API is a valuable tool for anyone who needs to obtain detailed information about SSL certificates used by a particular host. Its ease of use, comprehensive data, and potential applications make it a valuable asset for developers, security professionals, and website owners alike.

 

What are the most common uses cases of this API?

  1. Website owners can use the API to monitor the SSL certificates used by their own sites, ensuring that they are valid and up-to-date. By detecting and addressing any potential issues with their SSL certificates, website owners can help to maintain the security and trust of their sites.

  2. Third-party vendors and service providers can use the API to verify the SSL certificates used by the sites they interact with. This can help them to ensure that they are interacting with secure and trustworthy sites, and can detect potential security issues before they become problematic.

  3. Security researchers can use the API to analyze SSL certificates and detect potential vulnerabilities and threats. By examining the information provided by the API, researchers can identify potential weaknesses in SSL implementations and can develop new security tools and techniques to address these issues.

  4. Application developers can use the API to build security features into their applications. By verifying the SSL certificates used by the sites their applications interact with, developers can help to ensure that their applications are secure and trustworthy.

  5. IT administrators and network managers can use the API to monitor SSL certificates used on their networks. By regularly checking SSL certificates, administrators can detect potential security issues and ensure that all SSL certificates are valid and up-to-date.

 

Are there any limitations to your plans?

Besides API call limitations per month, there are no other limitations.

Zyla API Hub is, in other words, an API MarketPlace. An all-in-one solution for your developing needs. You will be accessing our extended list of APIs with only your user. Also, you won't need to worry about storing API keys, only one API key for all our products is needed.

Prices are listed in USD. We accept all major debit and credit cards. Our payment system uses the latest security technology and is powered by Stripe, one of the world’s most reliable payment companies. If you have any trouble with paying by card, just contact us at [email protected]

Sometimes depending on the bank's fraud protection settings, a bank will decline the validation charge we make when we attempt to be sure a card is valid. We recommend first contacting your bank to see if they are blocking our charges. If more help is needed, please contact [email protected] and our team will investigate further

Prices are based on a recurring monthly subscription depending on the plan selected — plus overage fees applied when a developer exceeds a plan’s quota limits. In this example, you'll see the base plan amount as well as a quota limit of API requests. Be sure to notice the overage fee because you will be charged for each additional request.

Zyla API Hub works on a recurring monthly subscription system. Your billing cycle will start the day you purchase one of the paid plans, and it will renew the same day of the next month. So be aware to cancel your subscription beforehand if you want to avoid future charges.

Just go to the pricing page of that API and select the plan that you want to upgrade to. You will only be charged the full amount of that plan, but you will be enjoying the features that the plan offers right away.

Yes, absolutely. If you want to cancel your plan, simply go to your account and cancel on the Billing page. Upgrades, downgrades, and cancellations are immediate.

You can contact us through our chat channel to receive immediate assistance. We are always online from 9 am to 6 pm (GMT+1). If you reach us after that time, we will be in contact when we are back. Also you can contact us via email to [email protected]
