Score any card BIN for fraud risk and rebill value, and get an instant approve / decline / decline decision โ with the reasons behind it. Sub-millisecond API for payment, fraud and affiliate teams.
BillionCore โ sub-millisecond BIN risk scoring
Turn any card BIN into a decision, not just metadata. In under 1ms you get an approve / review / decline call, a risk score with reasons, issuer data, and card-performance signals (rebill, refund, chargeback risk + projected LTV).
Most BIN APIs return brand/bank/country and stop. BillionCore returns a recommendation you can act on โ fast enough to run inline at checkout โ with the reasoning attached.
Who it's for
- Payments & fraud / e-commerce โ screen risky cards by BIN before you ship. Fewer chargebacks, cleaner revenue.
- Affiliate & media-buying teams โ flag BINs with poor rebill or high refund/chargeback performance before they erode margins. (Offer-side card performance โ not ad-account funding.)
Under the hood
- In-memory Go engine, sub-millisecond, lock-free reads
- Hot-reload, fail-safe, standard-library only
- Privacy-first: BIN only โ the full card number is never required or stored
Why it's different
- A decision, not homework
- Fast enough for the hot path
- Transparent โ every verdict lists its reasons
