title: How to use a symbol with a "." in the URL with Alphavantage?
body: <p>I am using the Alpha Vantage API and have come across a problem, every time I try to send an API request where the symbol (ticker) has a "." in it, the API call returns an Invalid API call error.</p>
  
  <p>How do I get past this?</p>
  
  <p>For example, to search for BT Group on the London Stock Exchange, you would use "LON:BT.A" which I would expect the formulate the URL like below:</p>
  
  <pre><code>https://www.alphavantage.co/query?function=TIME_SERIES_MONTHLY&amp;symbol=LON:BT.A&amp;apikey=API_KEY
  </code></pre>
  
  <p>This does not work, but equally if I wanted to search for a ticker without a dot then it works perfectly fine, for example Sky plc is "LON:SKY" so the below works:</p>
  
  <pre><code>https://www.alphavantage.co/query?function=TIME_SERIES_MONTHLY&amp;symbol=LON:SKY&amp;apikey=API_KEY
  </code></pre>
