GST API for India

GSTIN API is a GST API built specifically around the Indian GST regime — GSTIN structure, GSTR filing cycles, and e-invoicing rules — with INR pricing and no dependency on a foreign payment processor.

Why a GST API built for India, not adapted for it

Priced for the Indian market

INR pricing from ₹0.50 per verification, dropping to ₹0.40 at scale — no USD billing or currency conversion.

Built around Indian GST law

GSTIN structure, GSTR-1/GSTR-3B filing cycles, and e-invoicing thresholds as defined by the Indian GST regime.

No foreign payment gateway needed

Pay and manage credits without routing through an international processor — built for Indian businesses first.

Data hosted with Indian compliance in mind

Verification queries live GST records directly, with no third-party data resale in between.

GST API India — common questions

The right GST API for India depends on your use case, but the essentials to check are real-time (not batch) responses, INR pricing with no subscription lock-in, and complete taxpayer + filing + e-invoicing data in one call. GSTIN API is built around exactly those three.
Yes. GSTIN API is built for the Indian GST regime specifically — GSTIN format, GSTR-1/GSTR-3B filing cycles, and e-invoicing status — rather than being a generic tax-lookup API adapted for India.
No. Any business or developer, in India or elsewhere, can sign up, verify their email, and start making GST API calls immediately — no local registration is required to use the API itself.
It replaces manual, one-at-a-time lookups on the GST portal with programmatic access to the same underlying data — useful when verification needs to happen inside your own software rather than in a browser.
