The VAT Validation endpoint returns the company name, address, and validity status of the EU VAT number verified against the official VIES database.

Yes, the API offers a Batch Validation feature that allows users to process multiple VAT numbers, IBANs, or card numbers in a single request for bulk operations.
The API is designed for fintech applications, e-commerce checkout validation, KYC compliance, and accounting automation, helping businesses ensure the accuracy and validity of financial identifiers.
The Card Validation endpoint response includes fields such as "isValid" (boolean), "issuer" (card brand), "type" (credit or debit), "length" (number of digits), and "bin" (Bank Identification Number), providing essential details about the card.
The response data for the VAT Validation endpoint is structured in JSON format, containing fields like "vatNumber," "isValid," "country," and "checkDigitValid," allowing for easy parsing and integration into applications.
The Batch Validation feature allows users to submit multiple VAT numbers, IBANs, or card numbers in one request, returning a consolidated response with validity statuses and relevant details for each identifier, streamlining bulk processing.
Users can customize their requests by specifying the financial identifier type (VAT, IBAN, or card number) and providing the relevant identifier in the request body. Each endpoint accepts specific formats for the identifiers to ensure accurate validation.
The VAT Validation endpoint sources its data from the official VIES (VAT Information Exchange System) database, ensuring high accuracy and reliability in verifying EU VAT numbers against official records.
The Financial Validator API employs rigorous validation algorithms, such as the Luhn check for card numbers and official database checks for VAT and IBAN validations, ensuring that the data returned is accurate and reliable.
Typical use cases for the IBAN Validation endpoint include verifying bank account details during e-commerce transactions, ensuring compliance in financial services, and automating accounting processes to prevent errors in payment processing.

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.
