I’m trying to implement a getQuotes method and then a convert from one asset to another but I am getting an unauthorised response.

I’ve checked my API key and I’ve got read and Spot/Margin trading enabled so I can’t work out what’s going on.

My python code snippet is

timestamp = int(time.time() * 1000)
    query_string = f'fromAsset={from_asset}&toAsset={to_asset}&toAmount={amount}&recvWindow=5000&timestamp={timestamp}'
    signature = generate_signature(query_string, secret_key)
    url = f'{base_url}/sapi/v1/convert/getQuote'

    headers = {
        'X-MBX-APIKEY': api_key,
    }
    
    data = {
        'fromAsset': from_asset,
        'toAsset': to_asset,
        'toAmount': amount,
        'recvWindow': 5000,
        'timestamp': timestamp,
        'signature': signature
    }

    response = requests.post(url, headers=headers, params=data)  # Corrected from data=data to params=data

I’ve tried to find the relevant information in Binance docs but it’s not coming up with why it wouldn’t work without reading and spot/margin enabled.

I’m based in Australia but I’m able to please market and limit orders and also convert via Binance website.
