About the API:

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

This API will receive IBAN and it will provide the validation. If the number is valid, you will know it. Also, it retrieves additional information about the Bank as well, so you have further information about where the account is located. 


What are the most common uses cases of this API?

Validate your provider's IBAN 

With this API you will have the opportunity to validate the IBAN number of your provider before making any transactions. 

Recognize the country of the account only with Bank Account Number

You will be able to determine where the account is located. If there are any taxes that need to be applied to your transactions, you will be able to know beforehand. 

Compose IBAN numbers dynamically

This API is helpful to convert BBAN numbers to IBAN with ease. If you have to extend your bank details to someone outside your country, they will need IBAN, so you will automatically generate these numbers for them. 


Are there any limitations with 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 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.
