option_scrapper not working

[pavan-sahu-99]

May be the cookies from NSE website and headers might have been changed, getting an empty result while fetching results from option chain data

The api got changed, find the below edited code, i though of using the expiry function was getting null values so hardcoded it you can add this or can change this and if i find that api i'll integrate and post it

def nse_optionchain_scrapper(symbol = "NIFTY"):
indices = ['NIFTY','FINNIFTY','BANKNIFTY']
symbol = nse.nsesymbolpurify(symbol)
expiry_index = '09-Dec-2025'
expiry_equity = '30-Dec-2025'
if any(x in symbol for x in indices):
payload = nse.nsefetch('https://www.nseindia.com/api/option-chain-v3?type=Indices&symbol='+symbol+'&expiry='+expiry_index)
else:
payload = nse.nsefetch('https://www.nseindia.com/api/option-chain-v3?type=Equity&symbol='+symbol+'&expiry='+expiry_equity)
return payload

This worked well, thanks for the pointer.

Find below code completely edited included expiry dates:

import nsepython as nse
from datetime import datetime, timedelta

def format_expiry(date_obj):
return date_obj.strftime("%d-%b-%Y")

def get_weekly_expiries(today=None):
if today is None:
today = datetime.today()

year = today.year
month = today.month
d = datetime(year, month, 1)
expiries = []

while d.weekday() != 1:  # 1 = Tuesday
    d += timedelta(days=1)
while d.month == month:
    if d.date() >= today.date():
        expiries.append(format_expiry(d))
    d += timedelta(days=7)
return expiries

def get_monthly_expiry(today=None):
if today is None:
today = datetime.today()

year = today.year
month = today.month

if month == 12:
    next_month = datetime(year + 1, 1, 1)
else:
    next_month = datetime(year, month + 1, 1)
d = next_month - timedelta(days=1)

while d.weekday() != 1:
    d -= timedelta(days=1)

return format_expiry(d)

def get_current_expiry(symbol, today=None):
INDEX = "NIFTY"

if today is None:
    today = datetime.today()

# If SYMBOL is NIFTY - weekly + monthly
if symbol.upper() in INDEX:
    weekly = get_weekly_expiries(today)
    monthly = get_monthly_expiry(today)
    return weekly[0]

# INot nifty - only monthly
else:
    return  get_monthly_expiry(today)

def nse_optionchain_scrapper(symbol = "NIFTY"):
indices = ['NIFTY','FINNIFTY','BANKNIFTY']
symbol = nse.nsesymbolpurify(symbol)
expiry = get_current_expiry(symbol)
if any(x in symbol for x in indices):
payload = nse.nsefetch('https://www.nseindia.com/api/option-chain-v3?type=Indices&symbol='+symbol+'&expiry='+expiry)
else:
payload = nse.nsefetch('https://www.nseindia.com/api/option-chain-v3?type=Equity&symbol='+symbol+'&expiry='+expiry)
return payload

Instead of calculating the expiry dates via logic, you may invoke https://www.nseindia.com/api/option-chain-contract-info?symbol=BANKNIFTY contract info endpoint to get list of expiries per symbol
