## About

## What it does
BIN Lookup helps you identify a payment card’s issuing details from its BIN, or bank identification number. Send a BIN in the `bin` query parameter and get back a response envelope with a numeric `code`, a `success` flag, and additional module blocks in the body.

Use BIN Lookup when you need to confirm card metadata before processing a payment, routing a transaction, or enriching payment-related records. It is useful in checkout flows, fraud checks, payment analytics, and internal support tools where a card prefix needs to be mapped to issuer information.

The service is intentionally narrow: the request accepts a single string field, `bin`, and the response is centered on a simple success envelope. That makes it easy to wire into existing payment systems without having to handle a large payload or multiple required inputs.

If you are validating card-related data or looking up issuer context from a prefix, BIN Lookup gives you the basic lookup result in a format that is straightforward to consume.
