mfapi（mfapi 搜索）

MFapi Skill

Query Indian mutual fund data — NAV history, scheme info, search — using the free MFapi.in API.

Setup

No authentication or API keys required. The API is completely free and open.

Ensure curl and jq are installed:

# Debian/Ubuntu
sudo apt install -y curl jq

# macOS
brew install curl jq

What is an ISIN Code?

ISIN (International Securities Identification Number) is a 12-character alphanumeric code that uniquely identifies a security globally (e.g. INF200K01UT4). Indian mutual fund schemes have up to two ISINs:

• isinGrowth — identifies the Growth option of the scheme
• isinDivReinvestment — identifies the IDCW (Dividend) Reinvestment option (may be null)

ISIN codes are printed on CAS (Consolidated Account Statements), broker/demat platforms, and AMFI's website. They are stable identifiers — unlike scheme names, they don't change when a fund house rebrands.

Usage

Search schemes by name

curl -s "https://api.mfapi.in/mf/search?q=HDFC" | jq '.[] | {schemeCode, schemeName}'

List all schemes (paginated)

curl -s "https://api.mfapi.in/mf?limit=100&offset=0" | jq '.[] | {schemeCode, schemeName}'

Get latest NAV for a scheme

curl -s "https://api.mfapi.in/mf/125497/latest" | jq '{scheme: .meta.scheme_name, nav: .data[0].nav, date: .data[0].date}'

Get NAV history for a scheme

curl -s "https://api.mfapi.in/mf/125497" | jq '{scheme: .meta.scheme_name, records: (.data | length)}'

Get NAV history with date range

curl -s "https://api.mfapi.in/mf/125497?startDate=2023-01-01&endDate=2023-12-31" | jq '.data'

Get latest NAV for all schemes

curl -s "https://api.mfapi.in/mf/latest" | jq '.[:5]'

Endpoints Reference

Get Latest NAV by ISIN (Python)

The API doesn't support querying by ISIN directly. The scripts/get_nav.py script resolves ISIN → scheme code using a locally cached scheme list, then fetches the latest NAV.

How it works

1. Cache — Downloads the full scheme list (/mf, ~37k schemes) to /tmp/mfapi-schemes.json. Refreshes automatically if the cache is missing or older than 24 hours.
2. Lookup — Searches isinGrowth and isinDivReinvestment fields in the cache. If no match, refreshes the cache and retries.
3. Fetch — Uses the resolved scheme code to call /mf/{scheme_code}/latest.

Usage

# Single ISIN
python3 scripts/get_nav.py INF200K01UT4

# Multiple ISINs
python3 scripts/get_nav.py INF200K01UT4 INF846K01DP8

Example output

{
  "isin": "INF200K01UT4",
  "scheme_code": 119800,
  "scheme_name": "SBI Liquid Fund - DIRECT PLAN -Growth",
  "fund_house": "SBI Mutual Fund",
  "category": "Debt Scheme - Liquid Fund",
  "nav": "4277.67540",
  "date": "18-02-2026"
}

When multiple ISINs are passed, the output is a JSON array.

Notes

• Dates in responses use DD-MM-YYYY format; query params use ISO 8601 (YYYY-MM-DD)
• NAV values are strings with 5-decimal precision
• Scheme codes can be found via the search or list endpoints, or from AMFI's website
• The /mf endpoint returns all ~37,000 schemes; the Python script caches it locally at /tmp/mfapi-schemes.json to avoid repeated large fetches
• Cache auto-refreshes on ISIN lookup miss or after 24 hours
• No rate-limit headers are published, but the API asks for fair usage

Examples
