Fetch Card Details

Fetch a card’s current details and status.

Path: cardId (string, required) — the cardId from Generate Card.

Returns the stored card record only (no balance, no full PAN/CVV — use Generate Card Token for secure display). providerCardId is the card-issuer’s internal ID. updatedAt may be null.

All errors from this folder use { "status": "error", "message": "..." } and are returned as HTTP 400 (including “Card not found” — there is no 404). Success bodies use status: "success" (not success: true like the VTU endpoints).
