How to compare Aadhaar eSign API providers
Total cost, not the headline rate. Add platform fees, minimum commitments, and setup charges to the per signature price, then compare at your real monthly volume.
Time to first signature. Self serve signup and public docs mean you can build today. Sales led onboarding can take days or weeks before you get keys.
The eSign service provider behind it. Every Aadhaar eSign is issued by a licensed eSign service provider such as eMudhra, NSDL (Protean), or C-DAC. SignYu uses eMudhra.
Developer experience. Look for webhooks with signature verification, SDKs, an OpenAPI spec, and clear error codes.
Frequently asked questions
How much does an Aadhaar eSign API cost in India?
It depends on the provider and your volume. Many providers only share prices after a sales call. SignYu publishes its price: ₹999 per month for API access plus ₹15 per signature (credit packs of 10 or more, GST inclusive).
Why do most providers not publish their API pricing?
Many Aadhaar eSign API providers sell enterprise contracts with custom volume tiers, minimum commitments, and bundles with KYC products, so they quote each customer individually. That suits large buyers but makes it hard for startups and small teams to compare.
Is there a minimum commitment with SignYu?
No. There is no setup fee, no annual contract, and no minimum volume. You pay ₹999 per month for API access (with a 3-day free trial) and buy signature credits as you need them.
Does the price include GST?
Yes. SignYu credit prices are GST inclusive and every purchase comes with a GST invoice.
When is a credit used?
One credit is used per signer when you send a document. Creating documents, adding signers, and reading status are free.
