nepseman-api

Unofficial async Python client for Nepal Stock Exchange (NEPSE) market data. Not affiliated with NEPSE or nepalstock.com.np. Use at your own risk.

Reverse-engineers the authentication layer of nepalstock.com.np — including WASM-based token obfuscation and salt-based payload signing — with no dependency on any third-party NEPSE library.

Installation

pip install nepseman-api

Quick Start

import asyncio
from nepseman_api import NepseClient

async def main():
    async with NepseClient() as nepse:
        # Market status
        status = await nepse.market_status()
        print(status)

        # Today's prices
        prices = await nepse.today_price()
        print(prices[:5])

        # Price history for a stock
        history = await nepse.price_history("NABIL")
        print(history[:5])

asyncio.run(main())

await nepse.top_losers()       # Top losing stocks
await nepse.top_turnover()     # Top by turnover
await nepse.top_trade()        # Top by trade count
await nepse.top_transaction()  # Top by transactions

Indices

await nepse.nepse_index()          # NEPSE index value
await nepse.nepse_subindices()     # All sector subindices
await nepse.index_graph("banking") # Historical graph data

Securities

await nepse.company_list()              # All listed companies
await nepse.security_list()             # All securities with IDs
await nepse.sector_scrips()             # Grouped by sector
await nepse.company_details("NABIL")    # Company details
await nepse.daily_graph("NABIL")        # Intraday graph
await nepse.price_history("NABIL")      # OHLCV history (1 year default)
await nepse.price_history(
    "NABIL",
    start_date="2025-01-01",
    end_date="2025-12-31",
    size=500,
)
await nepse.market_depth("NABIL")       # Bid/ask depth (trading hours only)

Bulk History

# Fetch history for multiple stocks in parallel
results = await nepse.bulk_price_history(
    ["NABIL", "NICA", "ADBL"],
    start_date="2025-01-01",
    concurrency=5,
)
# {"NABIL": [...], "NICA": [...], "ADBL": [...]}

Floorsheet

await nepse.floor_sheet()                    # All trade records (paginated)
await nepse.floor_sheet(page=1, size=500)
await nepse.floor_sheet_of("NABIL")         # Filtered by symbol (first 500 rows only)

Note: floor_sheet_of() scans only the first size floorsheet records. NEPSE does not expose a per-symbol endpoint. For complete results, iterate floor_sheet(page=N) and filter manually.

Index Names

Valid values for index_graph():

nepse, sensitive, float, sensitive_float, banking, dev_bank, finance, hotel_tourism, hydro, investment, life_insurance, manufacturing, microfinance, mutual_fund, non_life_insurance, others, trading

Notes

• Trading hours — live_market() and market_depth() only return data Sun–Thu 11:00–15:00 NST
• Floorsheet — floor_sheet_of() filters client-side from the general floorsheet (NEPSE does not expose a per-symbol endpoint)
• SSL — NEPSE serves an incomplete certificate chain; the client bypasses SSL verification automatically
