Find score inside json result of PageSpeed Insights API v5

I think it is the following: json.lighthouseResult.categories.performance.score

Returns a decimal with 1 as maximum. So you have to multiply with 100 to get the percentage. Works for me.. However I don't seem to get the same value every time. It fluctuates...

It is json.lighthouseResult.categories.performance.score as described by Jeroen.

You can return all possible audit categories using the following example:

• URL: https://www.google.com/
• Return-Fields: lighthouseResult/categories/*/score
  • * is a wildcard
• Indentations (PrettyPrint): no
• Strategy: Desktop
• Categories:
  • Performance
  • Progressive Web App (PWA)
  • Best practices
  • Accessibility
  • SEO
• Api-Key: {YOUR_API_KEY}

  ---

  With these parameters, the API URL is:

  https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url=https%3A%2F%2Fstackoverflow.com%2F&fields=lighthouseResult%2Fcategories%2F*%2Fscore&prettyPrint=false&strategy=desktop&category=performance&category=pwa&category=best-practices&category=accessibility&category=seo&key={YOUR_API_KEY}

And the JSON-Response looks like this:

{
    "lighthouseResult": {
        "categories": {
            "performance": {
                "score":0.99
            },
            "accessibility": {
                "score":0.7
            },
            "best-practices": {
                "score":0.77
            },
            "seo": {
                "score":0.9
            },
            "pwa": {
                "score":0.56
            }
        }
    }
}
