 This app is running live on my personal server. Simply obtain a 511.org API key and hit `511-proxy.wn.zone`:
 
 ```
-https://511-proxy.wn.zone/transit/StopMonitoring?api_key=your-api-key&agency=SF&stopcodes=12345|67890&line_ids=5R|N|38&directions=IB|OB|N|S|W|E

 ```
 
 This returns the same API response format as the normal `StopMonitoring` endpoint, but with the `MonitoredStopVisit` array cut down to only the specified stop codes, lines, and directions specified in the URL. You may omit some or all of the filter params as you see fit.
