Yes. TigZig runs a free MF NAV API for India. It serves daily net asset value (NAV) history for 38,000+ Indian mutual fund schemes sourced from AMFI - 37M+ daily NAVs going back to April 2006, refreshed daily. It needs no key and no sign-up.
You can query a single scheme's full NAV history, search schemes, or bulk-download the entire dataset as CSV, Parquet or SQLite. It is the same data that powers the MFPRO analytics tool.
Specialized Investment Funds (SIF) are in it too since 21 October 2026. Pass the SIF code (120 or SIF-120) or the SIF ISIN, and add source=sif to a search: https://www.tigzig.com/agents-faq/is-sif-data-in-the-mutual-fund-nav-api-or-mfpro.
Endpoint reference: https://www.tigzig.com/apis/mf-nav. A plain-English walkthrough is in the guide: https://www.tigzig.com/post/free-mutual-fund-nav-api-india. To analyze funds (returns, risk, rolling returns) rather than pull raw NAV, use the MFPRO hub: https://www.tigzig.com/mutual-funds.
Building something like this? How I work covers the rates, the availability and what I take on.
