For example, to retrieve some evaluated data about this zettel you are currently viewing in [Sz encoding](00001012920516), just send an HTTP GET request to the endpoint `/z/00001012053500` with the query parameter `enc=sz`. If successful, the output is a symbolic expression value: # curl 'http://127.0.0.1:23123/z/00001012053500?enc=sz' (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 ") (LITERAL-INPUT () "{ID}") (TEXT " is a placeholder for the ") ... To select another encoding, you must provide the query parameter `enc=ENCODING`. Others are “[html](00001012920510)”, “[text](00001012920519)”, and some [more](00001012920500). In addition, you may provide a query parameter `part=PART` to select the relevant [part](00001012920800) of a zettel. # curl 'http://127.0.0.1:23123/z/00001012053500?enc=html&part=zettel' API: Retrieve evaluated metadata and content of an existing zettel in various encodings
