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

Simple to integrate

One REST GET endpoint, JSON, key auth, batch supported. Call it from any stack in minutes. Also on RapidAPI.

    There's a ton of those platforms, varying from extremely unknown to fairly well established. I'm pretty sure multiple of them end up as a Show HN every year. The only thing on your list they generally don't do is domain registration, but keeping that separate is generally a good thing. Sibling mentioned bearblog.dev, I'll mention write.as[1].

    I'd noticed some years back that this project seems to have started with a pretty strong anonymity story: https://write.as/ That seemed to diminish in emphasis a few years ago, stopped accepting accounts that didn't give you a credit card end of 2021, and some year recently (last year?
