Validates a UAE IBAN and returns the bank it belongs to. Useful for verifying a recipient's bank details before creating them.

This endpoint always returns 200 OK for a well-formed request — an invalid IBAN is not an error, it's reflected by valid: false in the response. When valid is false, country_code, bic_code, and bank_name are omitted, and an errors array is included instead, e.g.:

{ "iban": "AE0700000000000000000000", "valid": false, "errors": ["bad_check_digits"] }

Possible errors values: too_short, bad_chars, unknown_country_code, bad_length, bad_bban_format, bad_check_digits.
