The API that Walk Score provides is not easy to use because you have to provide GPS coordinates in order for it to work, basically ignoring the address you actually give it, which seems really silly.

This API just submits a request as if a user went to the site and typed an address into the bar, and then it returns the following data to you, no coordinates required:

• Walk Score
• Transit Score
• Bike Score
• The Walk Score URL with all the results

Either add this file to your web server, or use the version I have at https://stmhall.ca/walkscore.php.

There is 1 required param, and 1 optional param:

• addr: The address of the place you want to get the Walk Score for
• variable (optional): The name of a global variable to use to assign the results to (JSONP).

As mentioned, the variable param is only used for JSONP support, in case CORS ends up being a pain in the butt.

async () => {
    const response = await fetch('https://stmhall.ca/walkscore.php?addr=Rogers Arena Vancouver BC');
    const { walkScore, transitScore, bikeScore, url } = await response.json();
    console.log(walkScore, transitScore, bikeScore, url);
}

const script = document.createElement('script');
script.src = 'https://stmhall.ca/walkscore.php?variable=rogersArena&addr=Rogers Arena Vancouver BC';

script.addEventListener('load', () => {
    console.log(rogersArena);
});

document.body.appendChild(script);
