Re-stock & Price detection for JSON response

Is your feature request related to a problem? Please describe.

I'm getting an error when creating a price watch for a plain HTTP response that is JSON.

Describe the solution you'd like

If I don't use "Re-stock & Price detection for single product pages" and use the standard " Webpage Text/HTML, JSON and PDF changes" option I can get a change detection working using a jq filter.

I don't want to do that because I want the price threshold functionality from a "Re-stock & Price detection for single product pages" watch.

Is this possible and I am missing something or would this require a code change?

Describe the use-case and give concrete real-world examples

The JSON response looks like:

{
  ...
  "product_results": {
    ...
    "price: 15.0
  }
}

I think the check is failing because the extruct pkg can't handle parsing JSON. If it could get pass that step, the jsonpath_ng $..(price|Price) query would seem to work.

Moved to discussions because the issue template requires atleast the URL to be given or its impossible to test

whats the URL?

[wburningham]

This is the url. You need a token to query. An account is free.

"https://serpapi.com/search.json?engine=home_depot_product&api_key==html&product_id=206667220"

Let me know if you want me to paste the full json somewhere without auth

[wburningham]

I added a gist with the response JSON https://gist.github.com/wburningham/2741d1de8dec3fec291f9d8ec581e245

You should be able to use that as a URL for testing. @dgtlmoon let me know if I can provide something more.

Restock detection will NOT work for anything that is not LDJSON or similar specific JSON for machine readable restock/price information, it's just not what its designed for

so yes, use JQ here :)

The conditions ability will be covered by #2952 soon :)
