Json Path Finder API

POST https://api.findutils.com/api/tools/json-path-finder/execute

Returns every match of a JSONPath expression in a JSON document: the concrete path and value of each match, the match count, and a convenience "value" (the single value when there is one match, otherwise the array of values). Supports $.a.b, ["key"], [0], [-1], [1:3], wildcards (*), recursive descent (..name) and filters ([?(@.age > 30)]).
