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.

Start free โ€” 30-day Pro trial, no card.

Flask features and specs

  • Simplicity
    Flask is a micro-framework, meaning it is lightweight, easy to understand, and simple to use. It requires minimal setup to get a web application up and running.
  • Flexibility
    Flask provides flexibility and control over the application's architecture, allowing developers to choose the components they need and avoid unnecessary bloat.
  • Extensibility
    Flask supports various extensions to add capabilities like database integration, form validation, and authentication without compromising its core simplicity.
  • Documentation
    Flask has comprehensive and well-organized documentation, making it easier for developers to learn and implement features effectively.
  • Community
    Flask has a large and active community, providing ample resources like tutorials, code snippets, and third-party libraries that can help speed up development.
  • Testing
    Flask is designed to be unit tested easily, allowing developers to test their applications and ensure reliability.

Possible disadvantages of Flask

  • Scalability
    Flask may not be as scalable as some other frameworks for very large applications due to its minimalist design and lack of built-in features.
  • Boilerplate Code
    Since Flask requires you to integrate and configure many components manually, codebases in Flask can sometimes contain a lot of boilerplate code.
  • Opinionated Architecture
    While Flask provides flexibility, it also means there are fewer conventions. Developers must make more architectural decisions, which can be challenging for large team collaboration.
  • Limited Tools
    Compared to more comprehensive frameworks, Flask offers fewer built-in tools and features, which may necessitate additional plugins or custom implementations.
  • Learning Curve for Complex Applications
    While Flask is easy to learn for simple applications, it can become complex to manage as the application grows, requiring a good understanding of design patterns and software architecture.
