Automated Verification & Workflow APIs Built for Speed and Compliance.

KYC

Consent comes first, and the Aadhaar number comes back masked

Your request reaches the source register only after the person agrees to this check, for a purpose you name. What comes back is already reduced. You learn who the holder is without receiving the full Aadhaar number you would then have to protect.

1. 1You capture consent before the lookup, with the purpose recorded against it. The drawing uses customer onboarding, and a consent reference (cns_…) comes back beside the result.
2. 2The customer then enters a six-digit one-time code, one cell at a time, the way they would in your own flow.
3. 3The record comes back with aadhaar_number already masked to XXXX XXXX 4321. The first eight digits are never returned.
4. 4Name and date of birth come back as the register holds them, both masked to *** in this sample.

The masking happens at the source, before the response reaches you. Nothing you store from this check holds a full Aadhaar number.

Document OCR

Send a photograph, get back named fields

The reader takes whatever the applicant uploaded, whether that is a phone photograph, a scan or a page from a stack. It reads the page once, top to bottom, and turns each zone into a field with a name you can use in code. The response carries those fields and no image.

1. 1The slots carry their labels before the read starts. The field names stay the same when the document layout changes.
2. 2One pass runs down the page, and each zone resolves as the pass reaches it.
3. 3document_type comes back first. The reader names what it was given (IDENTITY CARD here) before reading anything off it.
4. 4holder_name and document_number arrive already named, with the name masked to *** and the number ABCDE1234F. Nothing downstream has to read a position on the page.

This is the generic reader in the family. Most of the other endpoints run the same steps against one kind of document, such as an invoice, a payslip or a lab report.

Banking

Does this account exist, and whose name is on it?

A penny drop credits one rupee to the account you are checking, then reads the registered name off the transfer that lands. You learn the name because a real credit went through and the bank says who accepted it.

1. 1₹1 leaves your float and travels to the account, against the IFSC in the request. This drawing uses EXMP0000123.
2. 2The answer comes back along the same path, and it carries the registered name.
3. 3The result records what it found and what it cost: name_at_bank masked to *** here, with ₹1 credited against the check that asked.
4. 4Its sibling, penny-less, answers the same question with ₹0 moved. The request looks the same and the four response fields are the same. You hold no float and have nothing to reconcile.

The pair shows how the catalog is organised. Each endpoint stands on its own instead of arriving in a bundle, and both of these run on the same API key.

Vehicle

One number plate returns the whole registration

You send the number painted on the vehicle, and the filed registration comes back one row at a time. It names the vehicle and the class it was registered as. It also carries the two dates that decide whether the vehicle can legally be on the road today.

1. 1You send rc_number exactly as it appears on the plate, such as MH 12 AB 1234.
2. 2You get maker_model and vehicle_class as filed. The sample record returns LMV, a light motor vehicle.
3. 3fitness_upto and insurance_upto are the two dates an operations team gates on. This record shows 2029-04-30 and 2027-01-22.
4. 4The ring at the end pairs the plate you asked about with the registration that answered. The record repeats the number back. You can see a mismatch instead of assuming one.

You can reach the same registration from a chassis number or an engine number when you do not hold the plate.

KYB

A GSTIN resolves to a company and its other registrations

Fifteen characters resolve to a legal entity. You get the name it is registered under, whether the registration is live, and the date it started. The response then lists every other registration filed against the same business PAN.

1. 1You send a 15-character GSTIN. You get legal_name exactly as registered, which reads SAMPLE TRADECO PVT LTD here.
2. 2The registration comes back with a status you can read straight off it: ACTIVE, registered 2019-07-02.
3. 3The record then opens out to the other registrations on the same PAN (ABCDE1234F in this drawing), each with the state it sits in.
4. 4Two more GSTINs appear here, in Maharashtra and Delhi. That is how a branch nobody mentioned turns up before you onboard the business.

Legal

What an eSign call returns after the signature

Signing is the quick part. The call returns a status, a certificate reference and a timestamp, because the record that matters is the one you can produce in a dispute later. You do not get back a picture of a signed page.

1. 1The agreement and the signatory's printed name sit on the page before anything happens.
2. 2Authorisation comes first, shown masked as an Aadhaar consent reading XXXX XXXX 4321. That consent is what reaches the execution step.
3. 3The signature is then drawn stroke by stroke, and the seal lands on the page after it.
4. 4You get back a status of SIGNED, its reference and the time it was executed: ESN-0000-4821 at 2026-08-14 09:12 in this sample.

Other endpoints in the same family change the authorising step, such as a one-time passcode, an eStamp or a DSC held on a token. They return the same evidence.

Corporate Registry

From a company number to the directors who can sign

A corporate identity number (CIN) resolves to the filed company record, and that record leads to the board sitting on it today. Check the directors before you give a company credit. Then you know who can sign for it.

1. 1You send a 21-character CIN. It resolves to the filed company: SAMPLE LOGISTICS PVT LTD, status ACTIVE.
2. 2The record then branches, one line per officer, into the board as the register holds it today.
3. 3Each officer returns as a DIN with the designation on file: managing director, whole-time director and independent director in this sample.
4. 4A DIN identifies a person without naming them. Run the same number the other way to see every board that person sits on.

Tax & Compliance

Check an invoice against the register that issued it

You can check an invoice against the register that issued it before you pay it. The call builds the reference from the invoice's own fields. The answer covers this document and no other.

1. 1The call reads three fields off the invoice and names them as it reads: supplier gstin, document no and document date.
2. 2All three travel to the register together. The reference comes from the document itself.
3. 3The invoice reference number (IRN) comes back row by row, with the acknowledgement date it was registered on: 14-08-2026.
4. 4VALID applies to this invoice, and the signed QR code returns to the slot that was drawn empty at the start.

The consignment check in the same family works the same way for goods already in transit.
