To fix this issue The JSON that's being returned from that endpoint doesn't quite match your model.
Here's the line where you tell your program how to parse the response:
code :
{
    "Meta Data": {
        "1. Information": "Daily Prices (open, high, low, close) and Volumes",
        "2. Symbol": "MSFT",
        "3. Last Refreshed": "2018-12-10 16:00:02",
        "4. Output Size": "Compact",
        "5. Time Zone": "US/Eastern"
    },
    "Time Series (Daily)": {
        "2018-12-10": {
            "1. open": "104.8000",
            "2. high": "107.9800",
            "3. low": "103.8900",
            "4. close": "107.5900",
            "5. volume": "39050766"
        },
        "2018-12-07": {
            "1. open": "108.3800",
            "2. high": "109.4500",
            "3. low": "104.3000",
            "4. close": "104.8200",
            "5. volume": "45044937"
        }...
    ...
    ...

Any of those help I came across this problem and this question, and after looking into the documentation I saw this Quote Endpoint that returns just the latest info. Here is the description:

help you fix your problem The data you have given appears to have a slight problem at the end (there is a trailing comma and open quote). Assuming that the actual data does not have this problem, you could extract the price into a float variable as follows:
code :
data = (' data ', {u'Global Quote': {u'05. price': u'108.2900', u'08. previous close': u'107.2800', u'10. change percent': u'0.9415%', u'03. high': u'108.8800', u'07. latest trading day': u'2018-11-16'}})
price = float(data[1]['Global Quote']['05. price'])
print(price)
108.29

wish helps you If you've generated an ExtWebComponents project, you could add these 2 files and declare the web component html element tag.
code :
<ext-cartesian 
  width="1000px"
  height="600px"
  downloadServerUrl="http://svg.sencha.io" 
  shadow="true"

will help you Close, as Bailey Kocin mentioned, you have to create an instance of the TimeSeries object and then call the function on that instance.
Try this instead:
code :
>>> from alpha_vantage.timeseries import TimeSeries
>>> API_KEY = 'XXXXXXXX'
>>> import matplotlib.pyplot as plt
>>> ts = TimeSeries(key=API_KEY)
>>> ts.get_daily(symbol = 'MSFT', outputsize = 'full')

With these it helps Yes, there is an undocumented BATCH_STOCK_QUOTES that lets you pass in a comma seperated list of ticker symbols.
Example HTTP GET request (use your apikey instead of xxx):
code :
{
    "Meta Data": {
        "1. Information": "Batch Stock Market Quotes",
        "2. Notes": "IEX Real-Time",
        "3. Time Zone": "US/Eastern"
    },
    "Stock Quotes": [
        {
            "1. symbol": "MSFT",
            "2. price": "119.1900",
            "3. volume": "10711735",
            "4. timestamp": "2019-04-09 14:39:53"
        },
        {
            "1. symbol": "AAPL",
            "2. price": "199.9100",
            "3. volume": "27681098",
            "4. timestamp": "2019-04-09 14:39:56"
        },
        {
            "1. symbol": "FB",
            "2. price": "177.1800",
            "3. volume": "14088849",
