Request Variants

Submit prefix (4–8 digits). Optionally include entity_id and query_context for MCR support.

Key Response Fields

For co-branded cards, bin_details may contain more than one entry — one per brand. Use query_context.supported_card_brands to filter results to brands your merchant accepts.

Supplying query_context.amount_details (amount + currency) enables automatic MCR brand selection if your entity is configured for Merchant Choice Routing.
