API: Retrieve metadata of an existing zettel

The endpoint to work with metadata of a specific zettel is /z/{ID}, where {ID} is a placeholder for the zettel identifier¹.

To retrieve the plain metadata of a zettel, use the query parameter part=meta

# curl 'http://127.0.0.1:23123/z/00001012053400?part=meta'
title: API: Retrieve metadata of an existing zettel
role: manual
tags: #api #manual #zettelstore
syntax: zmk

To return a JSON object, use also the query parameter enc=json.

# curl 'http://127.0.0.1:23123/z/00001012053400?part=meta&enc=json'
{"meta":{"back":"00001012000000 00001012053300","backward":"00001012000000 00001012053300 00001012920000","box-number":"1","created":"20210726174524","forward":"00001006020000 00001006050000 00001010040100 00001012050200 00001012920000 00001012921200","modified":"20220917175233","published":"20220917175233","role":"manual","syntax":"zmk","tags":"#api #manual #zettelstore","title":"API: Retrieve metadata of an existing zettel"},"rights":62}

Pretty-printed, this results in:

{
  "meta": {
    "back": "00001012000000 00001012053300",
    "backward": "00001012000000 00001012053300 00001012920000",
    "box-number": "1",
    "created": "20210726174524",
    "forward": "00001006020000 00001006050000 00001010040100 00001012050200 00001012920000 00001012921200",

  },
  "rights": 62
}

The following keys of the JSON object are used:

"meta"

References an embedded JSON object with only string values. The name/value pairs of this objects are interpreted as the metadata of the new zettel. Please consider the list of supported metadata keys (and their value types).

"rights"
