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.

Convex.dev features and specs

  • Seamless Deployment
    Convex.dev handles the infrastructure and deployment, allowing developers to focus on building applications rather than managing servers and scaling issues.
  • Real-time Data Synchronization
    Convex.dev provides built-in real-time data syncing which facilitates collaboration features and dynamic applications without additional configuration.
  • Backend as a Service
    Offers a back-end-as-a-service approach, which abstracts database and server management, allowing for rapid development and iteration.

Possible disadvantages of Convex.dev

  • Limited Customization
    As a managed service, there may be constraints on customization compared to building a backend from scratch, which might limit certain advanced configurations or optimizations.
  • Vendor Lock-In
    Relying on Convex.dev could lead to a degree of vendor lock-in, making it potentially difficult to switch providers or migrate to self-managed infrastructure in the future.
  • Pricing Complexity
    Potential users might find pricing complex or restrictive depending on usage patterns, especially if there is a high volume of data syncing or transactions.
  • Learning Curve
    Despite its abstractions, new users might encounter a learning curve to fully understand and leverage all of Convex.dev's functionalities effectively.
