This endpoint returns a predefined list of U.S. states, associated card BINs, and acceptable PAN (Primary Account Number) lengths. The data is static and designed for consumption by SDKs and partner integrations to facilitate client-side validation of state-specific card details.

Each entry in the response includes a two-letter state code, the corresponding BIN, and an array of valid PAN lengths for that state.

This endpoint is particularly useful for ensuring consistency and accuracy in front-end validation processes.
