Frequently Asked Questions

  • Yes, but you must have a premium subscription. Commercial use of the BIN API is not permitted on the free tier. See our pricing page to choose a plan that fits your needs.
  • Sign up for a free account to instantly get your API key, then pass it in the X-Api-Key header on every request. The documentation above includes ready-to-run examples in cURL, Python, JavaScript, Node.js, and more.
  • Your API requests will simply be denied once you hit your monthly quota — you will never be charged more than the plan you signed up for. To increase your quota, you can upgrade your plan any time on our pricing page.

  • Send a GET request to /v2/bin with the required bin parameter, which is typically the first 6 digits of a credit card number (e.g. bin=405316). You can create a free account to get an API key and try it out.
  • The API returns a JSON array of objects with fields such as bin, brand (e.g. Visa, Mastercard, American Express), type (credit or debit), categories, issuer, country_iso2, country, and is_valid. Several of these fields including brand, type, categories, issuer, and is_valid are available on premium plans.
  • The categories field is an array of tags describing the card, grouped by payment type (e.g. prepaid, credit, debit), cardholder segment (e.g. personal, business, corporate), card tier (e.g. basic, premium, luxury), and specialized use (e.g. travel, fleet, healthcare). This field is a premium feature; see the full category table on the documentation page above.
  • The BIN API is useful for payment validation, fraud screening, identifying a card's issuing bank and country, and routing transactions by card brand or type using fields like brand, issuer, and country.
