FAQ

What is a GSTIN API?+

A GSTIN API accepts an Indian GST identification number and returns validation status plus registered business fields as structured JSON.

How does GSTIN verification work?+

You send a GSTIN to the /v1/gstin endpoint with your API key. APISeeker validates the identifier and returns a normalized response for your application.

What data does the API return?+

Typical fields include validity, legal name, trade name, registration status and address components when available from the source.

How much does it cost?+

Each API has its own pricing tiers (Free → Scale) with separate monthly quota, rate limit and hard/soft limit settings. Open the Pricing tab on this page for GSTIN-specific plans.

What are the rate limits?+

Rate limits are per plan on this API — Free starts at 10 req/min. See the Rate limit tab for the full table. Limits are enforced by the API Gateway per key.

Is it suitable for production?+

Yes — the API is versioned under /v1, returns predictable errors and is designed for production onboarding workflows.
