Handling Unavailable Walk Scores
If a Walk Score is unavailable via the Walk Score API, show the text "Get Score" with a link to the property on Walk Score (ws_link).
If the request to the API fails entirely (network timeout, error response, etc.), this option can be used with a link to the Walk Score homepage instead (www.walkscore.com).
All of these requirements are implemented in our sample code.
