Frequently asked questions
What is a CIN?
The 21-character Corporate Identity Number assigned to every company registered in India. It encodes the listing status, industry, state, year and registration number.
Can I search by company name instead?
Yes — there is a separate endpoint that resolves a company name to its CIN, which pairs well with this one.
How much does the CIN Lookup API cost?
The CIN Lookup API on API Sathi starts at ₹1.50 per successful call plus 18% GST, paid from a prepaid wallet. There is no monthly fee or minimum volume, and recharges of ₹1,000 or more earn bonus credit. Live prices for every API are on the pricing page.
Can I test the CIN Lookup API for free?
Yes. Every account gets a TEST key that calls the CIN Lookup API in the sandbox at no cost and returns realistic sample responses, so you can finish your integration before adding money to the wallet.
Am I charged if a CIN Lookup API call fails?
No. You pay only for successful calls. If the source is unavailable, times out or rejects the request, the amount held for that call is released straight back to your wallet.
How do I get a CIN Lookup API key?
Sign up at apisathi.in — it takes about a minute — and create a key under API Keys. Use the TEST key in the sandbox, then recharge from ₹200 and switch to a LIVE key. The same key works for every API on API Sathi.
