The Check endpoint returns detailed information about an SSL certificate, including the subject and issuer details, validity dates, expiration information, and certificate fingerprints.
Key fields include "subject" (which contains organization details), "issuer" (providing the certificate authority), "validFrom" and "validTo" (indicating validity period), and "fingerprint" (for certificate identification).
The response is structured in JSON format, with nested objects for "subject" and "issuer," and fields for validity dates and fingerprints, making it easy to parse and utilize programmatically.
The Check endpoint provides information on the SSL certificate's validity, issuer details, organization information, and expiration status, helping users assess website security.
Data accuracy is maintained through regular updates from trusted certificate authorities and validation checks during the SSL certificate verification process.
Typical use cases include security audits, compliance checks, and monitoring SSL certificate validity for websites to ensure safe browsing experiences for users.
Users can customize requests by specifying the URL of the website they want to check, allowing for targeted SSL certificate validation for specific domains.
Users can expect consistent data patterns, such as structured JSON responses with clear fields for organization and issuer details, validity dates, and certificate fingerprints, facilitating easy integration.

To obtain your API key, you first need to sign in to your account and subscribe to the API you want to use. Once subscribed, go to your Profile, open the Subscription section, and select the specific API. Your API key will be available there and can be used to authenticate your requests.
You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.
No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.
Yes, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
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.
