How to get the starting price of a market's selection on in-play football markets?

[Gamblr]

My apologies if this has already been answered but I couldn't find anything conclusive searching the forum. Given any football market that's in-play (e.g., OVER_UNDER_05), I'd like to be able to check the starting odds for a particular selection within that market, is this possible at all? I tried using the SP_XXX price projections on listMarketBook/listRunnerBook but I don't seem to get the SP information on the response (tried with the API-NG Demo tool as well). Any help would be appreciated. Thanks

I recommend using the Betfair API's listMarketBook or listRunnerBook methods.

import requests

# Replace with your Betfair API credentials
app_key = "your_app_key"
session_token = "your_session_token"

# Market ID of the in-play football market
market_id = "1.1234567890"

headers = {
    "X-Application": app_key,
    "X-Authentication": session_token,
}

params = {
    "marketIds": [market_id],
}

response = requests.post("https://api.betfair.com/exchange/rest/v2/listMarketBook", headers=headers, json=params)

if response.status_code == 200:
    market_book = response.json()["result"][0]
    runners = market_book["runners"]

    for runner in runners:
        if runner["status"] == "ACTIVE" or runner["status"] == "SUSPENDED":
            selection_id = runner["selectionId"]
            starting_price = runner["startingPrice"]
            print(f"Selection ID: {selection_id}, Starting Price: {starting_price}")
else:
    print("Error fetching market book:", response.text)​

This code will retrieve the starting price for all active or suspended runners in the specified in-play football market. You can adjust the `market_id` and other parameters to match your specific needs.
