What is the update frequency of Grey Market Premium (GMP) data in your API?

Our GMP market intelligence engine continuously polls and updates live grey market premium quotes, percentage estimated listing gains, and Kostak rates every few minutes throughout Indian stock market trading hours.

Which Indian stock exchanges and segments are supported?

We provide 100% complete coverage for both NSE (National Stock Exchange) and BSE (Bombay Stock Exchange), covering both Mainboard public issues as well as SME IPOs listed on BSE SME and NSE Emerge.

How do I authenticate my API requests?

Authentication is straightforward and secure using HTTP request headers. Every API request requires passing your unique credentials via the X-API-KEY and X-API-SECRET headers.

Does the IPO API stream live bidding subscription multiples?

Yes! The /api/ipo/subscription-rates/:ipoId endpoint streams live subscription multiples for QIB, NII (both sNII and bNII), Retail Individual Investors (RII), and Employees directly updated during active exchange bidding sessions.

Can I access historical Basis of Allotment (BoA) data?

Yes. Through the /api/allotment/basis-records/:year/:ipoType endpoint, you can query decade-long registrar records including category-wise allotment ratios, lottery odds, and valid application counts.

Are there any free APIs available?

No, we do not provide free APIs. All our endpoints provide institutional-grade, real-time Indian IPO and GMP data under paid commercial subscriptions (Monthly, Quarterly, or Yearly) to guarantee high availability and sub-15ms edge latency.

What programming languages and frameworks are supported?

Because our service is a standard RESTful JSON API, it is compatible with any language or HTTP client. We provide official code snippets for cURL, JavaScript/TypeScript (Node.js/Axios), Python (Requests), PHP (cURL), and C# (.NET RestSharp).
