The [[endpoint|00001012920000]] to work with parsed metadata and content of a specific zettel is ''/z/{ID}'', where ''{ID}'' is a placeholder for the [[zettel identifier|00001006050000]].

A __parsed__ zettel is basically an [[unevaluated|00001012053500]] zettel: the zettel is read and analyzed, but its content is not __evaluated__.
By using this endpoint, you are able to retrieve the structure of a zettel before it is evaluated.

For example, to retrieve some data about this zettel you are currently viewing, just send a HTTP GET request to the endpoint ''/z/00001012053600''[^If [[authentication is enabled|00001010040100]], you must include the a valid [[access token|00001012050200]] in the ''Authorization'' header] with the query parameter ''parseonly'' (and other appropriate query parameter).
For example:
```{="sh"}
# curl 'http://127.0.0.1:23123/z/00001012053600?enc=sz&parseonly'
(BLOCK (PARA (TEXT "The ") (LINK-ZETTEL () "00001012920000" (TEXT "endpoint")) (TEXT " to work with parsed metadata and content of a specific zettel is ") (LITERAL-INPUT () "/z/{ID}") (TEXT ", where ") ...
```
Similar to [[retrieving an encoded zettel|00001012053500]], you can specify an [[encoding|00001012920500]] and state which [[part|00001012920800]] of a zettel you are interested in.
The same default values applies to this endpoint.
=== HTTP Status codes
; ''200''
: Retrieval was successful, the body contains an appropriate data value.
; ''400''
: Request was not valid.\
There are several reasons for this.
Maybe the zettel identifier did not consist of exactly 14 digits or ''enc'' / ''part'' contained illegal values.
; ''403''
: You are not allowed to retrieve data of the given zettel.
; ''404''
: Zettel not found.
You probably used a zettel identifier that is not used in the Zettelstore.
