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.
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.
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.
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.
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.
Besides API call limitations per month, there are no other limitations.
Check the validity of an SSL certificate, returns certificate information.

The SSL/TLS Certificate Verification API is a tool that allows developers to programmatically validate and authenticate SSL/TLS certificates used in secure web communications. It verifies key attributes such as certificate authenticity, expiration dates, and the certificate chain's integrity.
The API authenticates SSL/TLS certificates by checking their digital signatures against trusted Certificate Authorities (CAs) and verifying that they are not expired or revoked. It also validates the certificate chain to ensure that each certificate in the chain is valid and issued by a trusted authority.
The API supports standard SSL/TLS protocols (such as TLS 1.2 and TLS 1.3) and cryptographic standards (RSA, ECDSA) commonly used in securing web communications. It adheres to industry best practices and guidelines for certificate validation and cryptographic security.
Yes, the API can detect if a certificate has been revoked by checking Certificate Revocation Lists (CRLs) or using the Online Certificate Status Protocol (OCSP). It provides insights into the current status of certificates to ensure they are valid for use in secure connections.
The API validates the certificate chain by verifying that each certificate in the chain is signed by the issuer of the preceding certificate, up to a trusted root CA certificate. This ensures a complete chain of trust from the server certificate to a trusted root.
Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
Prices are listed in USD (United States Dollar), EUR (Euro), CAD (Canadian Dollar), AUD (Australian Dollar), and GBP (British Pound). 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 paying by card, just contact us at [email protected]
Additionally, if you already have an active subscription in any of these currencies (USD, EUR, CAD, AUD, GBP), that currency will remain for subsequent subscriptions. You can change the currency at any time as long as you don't have any active subscriptions.
The local currency shown on the pricing page is based on the country of your IP address and is provided for reference only. The actual prices are in USD (United States Dollar). When you make a payment, the charge will appear on your card statement in USD, even if you see the equivalent amount in your local currency on our website. This means you cannot pay directly with your local currency.
Occasionally, a bank may decline the charge due to its fraud protection settings. We suggest reaching out to your bank initially to check if they are blocking our charges. Also, you can access the Billing Portal and change the card associated to make the payment. If these does not work and you need further assistance, please contact our team at [email protected]
Prices are determined by a recurring monthly or yearly subscription, depending on the chosen plan.
API calls are deducted from your plan based on successful requests. Each plan comes with a specific number of calls that you can make per month. Only successful calls, indicated by a Status 200 response, will be counted against your total. This ensures that failed or incomplete requests do not impact your monthly quota.
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.
To upgrade your current subscription plan, simply go to the pricing page of the API and select the plan you want to upgrade to. The upgrade will be instant, allowing you to immediately enjoy the features of the new plan. Please note that any remaining calls from your previous plan will not be carried over to the new plan, so be aware of this when upgrading. You will be charged the full amount of the new plan.
To check how many API calls you have left for the current month, refer to the ‘X-Zyla-API-Calls-Monthly-Remaining’ field in the response header. For example, if your plan allows 1000 requests per month and you've used 100, this field in the response header will indicate 900 remaining calls.
To see the maximum number of API requests your plan allows, check the ‘X-Zyla-RateLimit-Limit’ response header. For instance, if your plan includes 1000 requests per month, this header will display 1000.
The ‘X-Zyla-RateLimit-Reset’ header shows the number of seconds until your rate limit resets. This tells you when your request count will start fresh. For example, if it displays 3600, it means 3600 seconds are left until the limit resets.
Yes, you can cancel your plan anytime by going to your account and selecting the cancellation option on the Billing page. Please note that upgrades, downgrades, and cancellations take effect immediately. Additionally, upon cancellation, you will no longer have access to the service, even if you have remaining calls left in your quota.
You can contact us through our chat channel to receive immediate assistance. We are always online from 8 am to 5 pm (EST). If you reach us after that time, we will get back to you as soon as possible. Additionally, you can contact us via email at [email protected]
To let you experience our APIs without any commitment, we offer a 7-day free trial that allows you to make API calls at no cost during this period. Please note that you can only use this trial once, so make sure to use it with the API that interests you the most. Most of our APIs provide a free trial, but some may not support it.
After 7 days, you will be charged the full amount for the plan you were subscribed to during the trial. Therefore, it’s important to cancel before the trial period ends. Refund requests for forgetting to cancel on time are not accepted.
When you subscribe to an API trial, you can make only 25% of the calls allowed by that plan. For example, if the API plan offers 1000 calls, you can make only 250 during the trial. To access the full number of calls offered by the plan, you will need to subscribe to the full plan.
