Usage

Mutual fund ISIN search

from casparser_isin import MFISINDb
with MFISINDb() as db:
    scheme_data = db.isin_lookup("Axis Long Term Equity Fund - Growth",  # scheme name
                                 "KFINTECH", # RTA
                                 "128TSDGG", # Scheme RTA code
                                 )
print(scheme_data)

SchemeData(name="axis long term equity fund - direct growth",
           isin="INF846K01EW2",
           amfi_code="120503",
           score=100.0)

Generic ISIN search

from casparser_isin import ISINDb
with ISINDb() as db:
    isin_data = db.isin_lookup('INE009A01021')

ISINData(
    isin='INE009A01021',
    name='INFOSYS LIMITED EQ FV RS 5',
    issuer='INFOSYS LIMITED',
    type='EQUITY SHARES',
    status='ACTIVE',
    symbol='INFY',
    exchange='NSE'
)

For listed equities, symbol / exchange carry the exchange trading ticker (e.g. INFY / NSE), resolved from NSE's equity list — handy for pricing a demat holding that's identified only by ISIN. They are None for instruments with no listed symbol (most bonds / AIFs). To resolve many ISINs in one DB session, use db.batch_isin_lookup([...]).

31-Jan-2018 NAV search

The database also contains NAV values on 31-Jan-2018 for all funds, which can be used for taxable LTCG computation for units purchased before the same date.

from casparser_isin import MFISINDb
with MFISINDb() as db:
    nav = db.nav_lookup("INF846K01EW2")
print(nav)

Decimal('44.8938')
