FastKYC API documentation

Common questions about KYC Verification APIs

What is a KYC verification API?

An API your application calls to check an identity document against the record that issued it, in real time, and receive the result as JSON. FastKYC's KYC APIs verify PAN against the income-tax record, Aadhaar number validity, driving licences against transport records, voter ID (EPIC) against electoral records and Indian passports, and return the holder details for your onboarding flow.

How does PAN verification work?

Send the PAN, and optionally the name and date of birth the customer gave you. The API returns whether the PAN is valid and the registered name; the comprehensive and advanced variants add status and Aadhaar-linkage, so you know the PAN is operative. The PAN Lite API returns the name alone for fast name matching.

Can I verify Aadhaar without an OTP?

Yes. The Aadhaar Validation API confirms a number is valid and in use without an OTP. For the holder's identity, address and photo, verify an offline Aadhaar eKYC XML (the API validates UIDAI's digital signature) or fetch the e-Aadhaar from DigiLocker with the customer's consent.

Is customer consent required?

Yes. Record the customer's consent before you run any verification. DigiLocker, CKYC download and EPFO flows go one step further: the customer authorises them with an OTP sent to their registered mobile number.

How fast are the checks?

Each check is a single API call that returns within the request, so a customer is verified while they are still in your onboarding flow rather than in an overnight batch.

Can I verify documents in bulk?

Yes. Every check is an API call you can run in parallel from your own system, and the PAN Lite API is built for bulk PAN validation at scale.

How much does KYC verification cost?

Pricing is per verification and depends on volume and the checks you use. Share your expected monthly volume and the team sends a rate card.

What else can I verify beyond PAN, Aadhaar, DL, voter ID and passport?

Vehicle RC and FASTag, CKYC records, mobile and email ownership, court records, company directors and more. Every check is listed in the Identity APIs section of the catalogue, each with its own page.
