Very simple endpoint not found error

Alpaca Integration Applications
1

The code below (just getting historic stock prices for TQQQ) returns
“Error fetching data: {“message”: “endpoint not found.”}”

I have tried data.alpaca.markets/, data.alpaca.markets/v1, data.alpaca.markets/v2

what should I be using?

import requests

Alpaca API endpoint

BASE_URL = “https://data.alpaca.markets/”

Your Alpaca API credentials

API_KEY = “xxx”
SECRET_KEY = “xxx”

Symbol and time frame for historical data

symbol = “TQQQ”
start_date = “2023-01-01”
end_date = “2023-05-13”

Request headers

headers = {
“APCA-API-KEY-ID”: API_KEY,
“APCA-API-SECRET-KEY”: SECRET_KEY
}

Fetch historical stock data

def get_historical_data(symbol, start_date, end_date):
endpoint = f"{BASE_URL}/bars/1D"
params = {
“symbols”: symbol,
“start”: start_date,
“end”: end_date,
“limit”: 1000
}

response = requests.get(endpoint, headers=headers, params=params)

if response.status_code == 200:
    return response.json()
else:
    print("Error fetching data:", response.text)
    return None

Call the function to get historical data

historical_data = get_historical_data(symbol, start_date, end_date)

Print the retrieved data

if historical_data:
for bar in historical_data[symbol]:
date = bar[“t”]
open_price = bar[“o”]
high_price = bar[“h”]
low_price = bar[“l”]
close_price = bar[“c”]
volume = bar[“v”]

    print(f"Date: {date}")
    print(f"Open: {open_price}, High: {high_price}, Low: {low_price}, Close: {close_price}")
    print(f"Volume: {volume}")
    print()

@learningtheropes The error endpoint not found is a bit misleading. The base url is ‘https://data.alpaca.markets/’ but the issue with the request is that the bars endpoint expects the timeframe to be a query parameter (like the other parameters) and not included in the URL as you had it. Including the timeframe ‘1D’ in the URL is what caused the error.

The code below does (I believe) what you want

import requests

# Alpaca API base URL
BASE_URL = 'https://data.alpaca.markets/'

# Alpaca API credentials
API_KEY = 'xxx'
SECRET_KEY = 'xxx'

# Request headers
headers = {
'APCA-API-KEY-ID': API_KEY,
'APCA-API-SECRET-KEY': SECRET_KEY
}

# Symbol and time frame for historical data
symbol = 'TQQQ'
start_date = '2023-01-01'
end_date = '2023-05-13'

# Fetch historical stock data
endpoint = 'v2/stocks/bars'
params = {
'symbols': symbol,
'timeframe': '1D',
'start': start_date,
'end': end_date,
'limit': 1000
}

response = requests.get(BASE_URL+endpoint, headers=headers, params=params)

response.json()
