This service uses data from 2 sources:

- Kuvera
- AMFI
- AMFI, via [Historical Mutual Fund Database](https://github.com/captn3m0/historical-mf-data)

## how

- A mapping between Kuvera Mutual Fund IDs and ISIN data is fetched from [kuvera-mutual-funds-lookup](https://github.com/captn3m0/kuvera-mutual-funds-lookup) as an automatically updating submodule.
- NAV data from AMFI is updated daily and saved in [_data/nav.csv](https://github.com/captn3m0/mf.captnemo.in/blob/main/_data/nav.csv)
- NAV data from AMFI is updated daily and published as a SQLite Database by https://github.com/captn3m0/historical-mf-data.
- This website takes the above, and publishes it via Netlify.

## license
