MF NAV API - Free Indian Mutual Fund NAV Data (AMFI)

Overview

AI agents: open (no auth), listed in the machine-readable catalog at api.tigzig.com/.well-known/api-catalog (RFC 9727). The base URL api.tigzig.com/mf/v1/ self-documents (endpoints, schema, file sizes); OpenAPI at /openapi.json.

A free, open AMFI mutual fund NAV API for India - no key, no sign-up. AMFI publishes NAVs as a giant daily text dump; most other "APIs" make you pull one scheme at a time, rate-limited, recent history only. This one does the thing others do not: let you download the entire NAV history - every scheme, every day - in a single call.

20.5M+ daily NAV records, refreshed daily from AMFI.
18,000+ schemes - every live and historical AMFI scheme.
History back to 2008, not just the last couple of years.
No authentication. No key, no sign-up, no quota games.

The same MF NAV data powers the MFPRO analytics app.

Using the API

1. Search for a scheme

Find a scheme code by name:

GET https://api.tigzig.com/mf/v1/search?q=hdfc flexi cap

Returns matching scheme codes and names (e.g. 118955 = HDFC Flexi Cap Fund - Growth - Direct Plan).

2. Full NAV history for one scheme

Pass the AMFI scheme code and get the ENTIRE history back - no pagination. Add &since=YYYY-MM-DD to filter by date:

GET https://api.tigzig.com/mf/v1/nav?scheme=118955&since=2020-01-01

3. Download the WHOLE database in one call

Instead of looping over 18,000 schemes, grab everything at once - a single pre-generated file (~130 MB for all 20M+ rows):

GET https://api.tigzig.com/mf/v1/download?format=parquet

Formats: parquet, csv.gz, tsv.gz, sqlite. Load straight into pandas:

import pandas as pd
df = pd.read_parquet("https://api.tigzig.com/mf/v1/download?format=parquet")
print(df.shape)   # every scheme, every day

Want sizes and last-refresh time first? Hit GET /mf/v1/downloads/manifest.

What you can build

A returns calculator (1Y / 3Y / 5Y / SIP / rolling returns) over the full history.
Backtests, fund-of-funds, and rebalancing strategies.
Your own dashboards and notebooks, without scraping AMFI.
Research-grade history, no subscription paywall.

Why one-call download matters: every other route makes you paginate - one scheme, one request, rate-limited, often capped at recent history. For any real analysis you need all of it, locally. One call, one file, done.
