National ID validation API

This web service provides a fast, accurate, and standardized tool for validating Iranian National Identification Numbers (Code Melli) based on official algorithmic checks.

Upon submitting the national code, the API evaluates character length, detects repeated sequence patterns, and calculates the official check digit, returning an instant validation result in a structured JSON format.

It is an essential solution for integration into user registration flows, KYC pipelines, e-commerce checkouts, and user dashboards to filter invalid entries and ensure database accuracy.
