e-Stamp Paper API
Buy electronic stamp paper for any state, programmatically.
What the e-Stamp Paper API does
Create an electronic stamp-paper order for the state you are executing in, and receive the stamped document as a PDF. Stamp duty is passed through at cost — you pay the state exactly what the state charges — with a flat service fee on top. Articles (the head of charge under each State Stamp Act) are state-specific and available through a companion lookup.
Popular use cases
- →Loan and hypothecation agreements that must be executed on stamp paper
- →Rental and leave-and-licence agreements at volume
- →Affidavits and power-of-attorney documents for operations teams

Frequently asked questions
Which states are supported?
Articles are published per state and change over time; query the articles endpoint for the state you are stamping in. An article valid in Rajasthan is not valid in Maharashtra.
How is stamp duty charged?
At cost. You are billed a flat service fee plus the exact duty the state levies, including any state surcharge — Rajasthan adds 30% on the duty, and that follows the stamp, not your billing address.
How much does the e-Stamp Paper API cost?
The e-Stamp Paper API on API Sathi starts at ₹60 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.

Yes. Every account gets a TEST key that calls the e-Stamp Paper API in the sandbox at no cost and returns realistic sample responses, so you can finish your integration before adding money to the wallet.
