Fed Treasury vs Razorpay IFSC

Fiscal Data is the U.S. Department of the Treasury's open REST API for federal financial datasets — debt, revenue, spending, interest rates, and savings bonds — maintained by the Bureau of the Fiscal Service. Every endpoint supports field selection, filtering, sorting, and pagination, and returns JSON by default with CSV or XML available via the format parameter. No registration or API key is required, and a live Origin-header probe confirmed CORS is enabled (Access-Control-Allow-Origin: *).

Razorpay's IFSC Toolkit is a free, keyless lookup over India's Indian Financial System Code directory, compiled from RBI and NPCI public data, returning the bank, branch, address, and supported payment rails (NEFT/RTGS/IMPS/UPI) for any given code. The underlying dataset and API server are open-sourced on GitHub, with official client libraries for Node, PHP, Ruby, and Go.
