FAQs

What is a GST Search & Monitoring API?

A service that allows you to programmatically verify a business’s GST registration status (Active, Cancelled, Suspended), fetch its legal details, and set up alerts for any future status changes all without manual checks on the GST portal.

Why should I use an API instead of checking the GST portal manually?

The API automates and scales verification. It’s essential for onboarding dozens of vendors, monitoring hundreds of existing partners for compliance risks, or integrating real-time checks directly into your loan approval or e-commerce seller workflows.

Do you support all GSTINs in India?

Yes, our API covers the search and verification of all valid GSTINs (Goods and Services Tax Identification Numbers) issued across India.

Can I verify GSTINs in bulk?

Absolutely. Our Bulk Search endpoint allows you to submit a list of up to 10,000 GSTINs in a single API call and receive a consolidated report, perfect for large-scale vendor audits or portfolio reviews.

Do you provide a dashboard, or is it only API-based?

We offer both. You can integrate the API directly into your systems, or use the SignalX web dashboard to run single searches, view monitoring alerts, and download reports manually.
