Many of us are familiar with systems that can determine the issuing bank and underlying infrastructure of a credit card by simply entering the card number on a website.

In reality, achieving this is not very complex. As illustrated in the attached image, each card has a BIN code (the first 4-6 digits of the card number). By analyzing these codes, bank information can be easily obtained.

The reason why there is no up-to-date API for this purpose is quite clear. Although not frequently, BIN numbers can change. Therefore, I have prepared a JSON file that you can use in your projects. This file contains up-to-date data and can be easily imported to perform queries.

If BIN codes change in the future, necessary additions can be made.

Best regards to everyone!
