Face Liveness Check API

Face Liveness Check API

Check if the selfie your users take is indeed live, optimally clicked to save in your records, if there are multiple faces detected in the image, and what percentage of the image the face actually covers.

About the API:

Face liveness detection helps you uncover fraud by ensuring that the image you have been provided isn’t a picture of a picture, a passport-sized image, or an image of another individual on a cell phone/laptop screen. Pair it with the Face Comparison Validator API to have complete confidence that the selfie of the individual is indeed live, and belongs to the same individual as you expect. 


What this API receives and what your API provides (input/output)?

This API will receive the image URL that you want to check its liveness. It will provide information like face quality, if the photo is live taken, and its position in the image. 


What are the most common uses cases of this API?

Fraud detection: Face liveness detection helps you uncover fraud by ensuring that the image you have been provided isn’t a picture of a picture, a passport-sized image, or an image of another individual on a cell phone/laptop screen.

Check image properties: Be able to detect if any image is not following your requirements. Check if the face is too far from the camera if its quality is good or poor, and avoid your users to upload images that won't be useful for your platforms.  

Receive images for biometric analysis: If you are using biometric analysis in your products, is important to receive images that are taken live from your users. This API will help you with that. 


Are there any limitations to your plans?

Besides the number of API calls 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 worldโ€™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 โ€” plus overage fees applied when a developer exceeds a planโ€™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.
