No key, no sign-up

Call it from your server or straight from a browser. CORS is open, and every answer has the same { data, meta } shape.

Open source

The code is on GitHub under AGPL-3.0. Every response names its data source, its version and its licence.

Private by default

No cookies, no tracking, no IP addresses in the logs. Personal values you send are never logged. Details

Every API.

Each has its own page with parameters, a real response and code to copy.

Guides.

Real tasks, solved with code you can paste.

Bank holidays, working days and T+1 settlement datesFind whether a date is a bank holiday in a state, the next working day, N working days ahead, and NSE settlement dates, in Python.Check a GSTIN or PAN before you save itCatch typing mistakes in GSTINs and PANs with the check character, and read the state and PAN out of a GSTIN, in JavaScript.Fill city and state from a pincode in a web formLook up the district and state as soon as someone types a six-digit pincode, with plain JavaScript and no API key.Make a UPI payment QR code for an amountGenerate a QR code that any UPI app can scan to pay a set amount to your UPI ID, or a upi://pay link for a button on mobile.Remove Aadhaar, PAN and phone numbers before sending text to an LLMMask Indian personal identifiers in text before it reaches a language model or a log, with check-digit validation so ordinary numbers are left alone.Show NSE and BSE company logos in your appPut a listed company's logo in an img tag by ticker or ISIN, as SVG or sized PNG, with an initials tile when no logo exists.Show the bank and branch for an IFSC codeTurn an IFSC into a bank name, branch and address, and check that the branch takes NEFT, RTGS, IMPS or UPI before you send money there.Write rupee amounts in words for invoices and chequesSpell an amount the Indian way, with lakh and crore, rupees and paise, in English, Hindi or Tamil.

Questions.

Is it free?

Yes. There is no API key, no sign-up and no paid plan. Each client can make 600 requests a minute; a few endpoints that do heavy work count as more than one.

Can I use it in a commercial app?

Yes. Calling the API puts no licence on your app. The data keeps the licence of its source, named in every response under meta.source; a few sources ask for a credit line. The code examples on this site are MIT-0, so you can paste them anywhere.

Where does the data come from?

From official publications such as the Reserve Bank of India, India Post, NSE and the GST council, and from open datasets such as OurAirports and Wikipedia. Every response says which source it used, its version and when it was retrieved.

What do you log?

One line per request with the path, the status and the time taken. IP addresses are never written to the log, and endpoints that take personal values (phone numbers, email addresses, text you send) leave their input out of the log entirely.

Can I run it myself?

Yes. The whole service is open source under AGPL-3.0: one Go program and its datasets. The README explains how to build and run it.

Does it work with AI assistants?

Yes. There is an MCP server at /mcp with no authentication, an Agent Skill, a Claude Code plugin, an OpenAPI description and llms.txt.
