India MF Tool Builders: You Do Not Need a Thousand API Calls a Day. The Whole NAV Dataset Is One File.
Published: September 4, 2026
India MF tools builders: if you are using the Tigzig MF API to update NAV daily for say a thousand funds in your tool, you do not need a thousand API calls. The whole dataset is published as one file. Parquet is about 168 MB and has every scheme and every NAV date we hold. Download it once, load it into your own database, and query it locally from then on.
To stay current, point an hourly cron at the manifest. It is a small JSON file, under 5 KB, that lists every download with its size, its row count and the time it was built. Read the build time, and if it has moved since your last run, pull the big file again.
If you would rather not download even that, the manifest carries an ETag, which is a version tag for the file as it stands right now: send that tag back on your next request and you get a 304 Not Modified with no content at all, so nothing transfers until something has actually changed.
If all you want is the latest NAV for every scheme, there is a daily snapshot file also .. which also acts as a scheme master and does the same job at about a megabyte, and one download covers every fund.
Free, no signup, no API key.
