Cielo BIN Query API is one of 13 APIs that [Cielo](https://apis.io/providers/cielo/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include BIN, Card Validation, and Lookup. The published artifact set on APIs.io includes API documentation.

The Cielo BIN Query service returns metadata for a card BIN (Bank Identification Number) — issuing brand, card type, and additional rules — so e-commerce checkouts can validate the data shoppers enter before authorization. It is exposed via the Cielo e-Commerce query endpoint GET /1/cardBin/{BIN} and via dedicated mobile SDKs.
