Also of interest is RFC 6901, JSON Pointer, https://tools.ietf.org/html/rfc6901. That spec is much simpler (and syntactically incompatible, I may add), providing unique paths to elements inside a JSON document, and not handling any sorts of queries, as these Jsonpath and JSONPath things both do.
JSON Pointer is not ubiquitous by any means, but it does got use in diverse APIs. Most recently, JMAP uses it for backreferences.
(The naming of these things is a mess. XPath deals in what you could call queries or selectors, not what I would be willing to call paths; JSONPath adopted XPath’s bad name presumably for marketing reasons, and so what became RFC 6901 presumably went with the name JSON Pointer instead of the obvious name of JSON Path to avoid confusion, as it was coming well after JSONPath.)
