title: Binance API: symbol price ticker. What delimiter for several symbols?
body: <p>Binance provides good API documentation but in some cases, it looks either incomplete or unclear at least.
  Symbol Price Ticker: <a href="https://binance-docs.github.io/apidocs/spot/en/#symbol-price-ticker" rel="noreferrer">https://binance-docs.github.io/apidocs/spot/en/#symbol-price-ticker</a></p>
  <p><strong>Question:</strong> is there a way to get prices just for several symbols (more than one but not a complete list)? It looks illogical but seems Binance handles either a single symbol or an entire list at once. Attempts to use different delimiter (like: &quot;,&quot;, &quot;;&quot;, &quot;+&quot;, &quot;|&quot;, etc) leads to an error:</p>
  <p><em>request</em>: <code>api/v3/ticker/price?symbol=DOGEUSDT,ETHBTC</code></p>
  <p><em>response</em>: <code>Illegal characters found in parameter 'symbol'; legal range is '^[A-Z0-9-_.]{1,20}$'</code></p>
  <p>As a result, integration code is not optimal - developers have to send several similar requests or extract required data from hundreds of items.</p>
