Credit Card Validator - BIN Checker API

Credit Card Validator - BIN Checker API

With this API you will be able to detect if any credit card is valid when it's making any transaction on your website.

About the API:

This API is intended to help you spot fraudulent credit card transactions. Start verifying, validating, and checking all information on credit/debit cards just using BIN numbers.

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

The user will send the credit/debit card (Bank Identification Number) or IIN (Issuer Identification Number) to get the full details.

You have to provide a BIN (Bank Identification Number) - the first 6 digits of a credit/debit card, to receive the full details of this BIN/IIN in JSON format. 

You will receive the card's validity, if it's VISA or MASTERCARD, what is the issuing bank, and the card's issuing location. 

What are the most common uses cases of this API?

This API is ideal for those who are wanting to implement a payments gateway on their pages. This API will help those purposes because it will recognize if the card is invalid. 

This is also helpful to recognize the issuing bank or entity. So if you have special offers with a specific bank you will be able to authorize the transaction or not.  

Are there any limitations with your plans?

Besides API call limitations per month: 

  • Basic Plan: 1000 API calls per day.
  • Pro Plan: 1000 API calls per day. 
  • Pro Plus Plan: 10k API calls per day

The API allows developers to validate and verify credit card information using the Bank Identification Number (BIN). By providing the first six digits of a credit card, the API can detect the issuing bank, issuing entity (e.g., VISA, Mastercard), the card's location, and whether it is a valid credit card or not.

The API follows a secure approach by only requiring the Bank Identification Number (BIN), which consists of the first six digits of a credit card. This approach avoids the need to transmit or store sensitive credit card details.

The API response includes comprehensive details about the credit card. This includes information such as the card's validity (whether it is valid or not), the issuing bank's name, the card brand (e.g., VISA), the card type (e.g., credit), the card level (e.g., purchasing with fleet), the currency associated with the card, and the country of issuance. Additionally, the response provides contact information for the issuer, including their name, website, and phone number.

To access the API, you need to make an HTTP POST request to the API endpoint, providing the first six digits of the credit card (BIN) as a parameter. The API will then respond with a JSON object containing the requested information about the credit card, including its validity, issuing bank details, and location information. You can integrate this API into your application or system to leverage its functionality and enhance your credit card processing capabilities.

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, look at the ‘X-Zyla-API-Calls-Monthly-Remaining’ header. For example, if your plan allows 1000 requests per month and you've used 100, this header will show 900.

To see the maximum number of API requests your plan allows, check the ‘X-Zyla-RateLimit-Limit’ 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.
