API Deposu's Turkey-specific form validation API. It provides IBAN checksum, phone normalization, TCKN/VKN checksum, province/district lookup, text/address normalization, and bulk validation endpoints.
Catalog notes to consider when evaluating the integration, in addition to the provider documentation.
This is a first-party API Deposu product; it does not verify official registry status, real identity/VKN records, current operator ownership, UAVT/address codes, or bank account ownership. TCKN/VKN validation is format/checksum only, and IBAN validation is format/checksum plus static payment provider code lookup. Phone operator output is returned only as a prefix-based possibleOriginalOperator hint.
