About GSTIN API

GSTIN API exists to remove one specific piece of manual work from Indian businesses: checking whether a GST number is real, active, and compliant. What used to mean logging into the GST portal and searching by hand is now a single API call.

We built the product for the workflows we kept running into ourselves — verifying a vendor before onboarding them, confirming a customer’s GSTIN before raising an invoice, and checking filing status before extending credit terms. Those are the use cases the API is optimized for.

As a GST verification API India-based teams actually rely on day to day, we care most about accuracy and uptime — the two things that matter when a compliance check sits in the middle of a live business process.

What we care about

Accuracy first

Every response comes from live GST records, not a cached snapshot. If a GSTIN changed status this morning, the API reflects it now.

Built for developers

We designed the API the way we would want to consume it ourselves: one endpoint, one header, predictable JSON, no surprise breaking changes.

India-first, India-built

As a GSTIN API company built in Surat, Gujarat, we focus specifically on the GST compliance workflows Indian businesses actually run into — vendor onboarding, invoicing, and filing checks.
