}Check the format and check digits of one identifier: IBAN (ISO 13616, per-country length and layout), BIC/SWIFT (ISO 9362 format and country), EU VAT number (offline checksum, VIES not queried), GTIN/EAN-8/UPC-A/EAN-13/GTIN-14 (GS1 mod 10) or ISBN-10/13. type "auto" (default) detects the type from the shape. Returns valid, a reason when invalid (e.g. the expected check digit), and normalized/formatted forms. Format check, not a compliance check: valid does not mean the account, registration or product exists. The code is sent in a POST body and not stored or logged. Read-only. Same engine, keys and limits as POST /v1/{type}.
| Argument | Type | Description |
|---|---|---|
| code* | string | The identifier to check, e.g. "DE89 3704 0044 0532 0130 00", "ATU13585627", "4006381333931" or "978-0-306-40615-7". Spaces, hyphens and dots are ignored. Max 64 characters. |
| type | string | auto (default), iban, bic, vat, gtin or isbn. |
