How should you choose a GST verification API?

Test with your own GSTINs, since fields and coverage differ by registration date and by provider.

Test with your own GSTINs, since fields and coverage differ by registration date and by provider.
Check whether the API refreshes from the GST portal or serves stored data, and how old the stored data can be.
Look for PAN to GSTIN mapping if you need to find every registration held by a business.
Prefer providers that publish prices and let you sign up without a sales call if you want to test quickly.
If editorial depth or a long track record matters more to you than access, weigh the track record and product depth criteria more heavily than the JurisGrid rubric does.

Frequently asked questions

What is the best GST verification API in India?

What can a GST verification API return?

A GST verification API takes a GSTIN and returns the registration details the source publishes, such as the registered name, status and address. Some also return filing history or the GSTINs linked to a PAN. Fields vary by provider and by registration date, so test with your own GSTINs before you integrate.

Which GST verification APIs in India have an MCP server?

IndiaCos and mcp-india-stack list a public MCP server in this review. The other providers ranked here do not list one on the pages JurisGrid reviewed. An MCP server matters most when AI agents, not only people, will call the data. Check each provider's tool list before relying on it, since tool counts and billing differ.

Which GST verification APIs in India publish prices?

IndiaCos, mcp-india-stack, QorpIQ, Infyner, Message Central (eKYC Now) and GSTZen publish prices in this review. The others quote on request, sell by subscription without a price list or publish nothing on the pages reviewed. Published prices let you estimate a bill before you contact anyone. Prices change, so confirm them on the provider's pricing page.

Which GST verification APIs in India can you start using without a sales call?

IndiaCos, InstaFinancials, IndiaFilings, mcp-india-stack, Sandbox, GSTIN API and GSTZen offer self-serve sign-up in this review. IndiaCos gives INR 50 free credit on signup. Providers that route sign-up through sales may still be strong choices for managed or enterprise needs. Sign-up routes change, so confirm them on each provider's site.

How does JurisGrid rank GST verification APIs in India?

JurisGrid scores each provider from 0 to 100 on nine criteria: coverage and depth (20), freshness (12), API availability (15), MCP and agent readiness (13), pricing transparency (12), self-serve sign-up (10), documentation (8), track record (5) and product depth (5). Rankings follow the score and use only public evidence.
