      description: API key issued at https://ibanchecker.cash/api-docs; the free key covers 100 requests a month of single validation. Required for every endpoint except /formats. Bulk validation and BIC lookup need the Basic plan, extraction the Growth plan; a free key whose address has a verified ibanchecker.cash account can try them (up to 10 IBANs per bulk call, 5,000 characters per extraction). Bulk and extraction count one request per IBAN. /formats works without a key, up to 100 requests an hour per IP.
