Frequently asked questions
Can I search by TAN instead of by name?
This endpoint searches by company name and returns matching TANs with a confidence score. Use the company lookup APIs if you are starting from a registration number.
What does the match score mean?
How closely the registered name matches what you sent. A perfect match scores 100; anything lower is worth reviewing before you rely on it.
How much does the TAN Verification API cost?
The TAN Verification 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 TAN Verification API for free?
Yes. Every account gets a TEST key that calls the TAN Verification 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 TAN Verification 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 TAN Verification 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.
