Indian Mutual Fund vs OpenFIGI

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`.

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`.
