# CIN Verification API Reference

`POST https://staging.eko.in/ekoapi/v3/tools/kyc/cin`

Verify Company Identification Numbers (CIN) against MCA records — returns company name, incorporation details, directors, and CIN status.

The CIN Verification API lets you validate a Company Identification Number (CIN) against Ministry of Corporate Affairs records in real time. It returns the registered company name, registration number, incorporation date, CIN status (active / struck-off / dormant / under liquidation), company email, country of incorporation, and a full list of directors with their DIN, designation, address, and date of birth. Use it for KYB onboarding, vendor due diligence, lending workflows, and corporate compliance checks.
