OpenFIGI vs Razorpay IFSC

OpenFIGI is Bloomberg's free public API for the Financial Instrument Global Identifier (FIGI) standard, mapping third-party symbology (tickers, ISINs, CUSIPs, SEDOLs) to FIGIs across equities, options, futures, and indices, plus full-text search and a bulk spreadsheet-upload tool. A live test of the mapping endpoint returned real data with zero API key supplied, capped at 25 requests per 60 seconds — the entry's stored `API Key` auth is corrected to `None`, since registering for a free key only raises that throughput ceiling rather than gating access. A live Origin-header probe (an OPTIONS preflight and a real POST) found no Access-Control-Allow-Origin header on either response, correcting the stored `cors: yes` to `no`.

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.
