IG vs Indian Mutual Fund

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`.

MFapi.in serves free, keyless access to India's mutual-fund NAV history — scheme metadata and full daily NAV time series for 10,000+ schemes registered with AMFI, refreshed six times a day from AMFI's own bulk feed. Responses are plain JSON with no authentication, rate limiting, or usage caps, and the project publishes an interactive Swagger UI covering every endpoint. A live Origin-header probe against the real API host (api.mfapi.in) confirmed CORS is enabled, returning `Access-Control-Allow-Origin: *` — resolving the previously-stored `unknown`.
