IG vs Razorpay IFSC

IG's trading API layers REST order execution and Lightstreamer-based streaming onto the same CFD, spread-betting, and forex engine behind IG's own platform, authenticated with an API key generated from a live account (a linked demo account then lets you sandbox trades risk-free). There's no separate API fee — access is included with any account and gated only by IG's standard per-key usage quotas, not a metered price. A live probe of the real API host (api.ig.com) returned `Access-Control-Allow-Origin: *` even on an error response, confirming CORS is open — correcting the previously-recorded `unknown`.

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.
