Neutrino API
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.
One REST GET endpoint, JSON, key auth, batch supported. Call it from any stack in minutes. Also on RapidAPI.
Start free โ 30-day Pro trial, no card.
