API Reference

GET `/`

Return the index page.

GET `/<name>[.<ext>]` or `/<name>/<filename>`

Fetch the paste with name <name>. By default, it will return the raw content of the paste.

The Content-Type header is set to the mime type inferred from the filename of the paste, or text/plain;charset=UTF-8 if no filename is present. If <ext> is given, the worker will infer mime-type from <ext> and change Content-Type. If the paste is uploaded with a filename, the worker will infer mime-type from the filename. This method accepts the following query string parameters:

The Content-Disposition header is set to inline by default. But can be overriden by ?a query string. If the paste is uploaded with filename, or <filename> is set in given request URL, Content-Disposition is appended with filename* indicating the filename. If the paste is encrypted, the filename is appended with .encrypted suffix.

If the paste is encrypted, an X-PB-Encryption-Scheme header will be set to the encryption scheme.

If the paste is uploaded with a lang parameter, an X-PB-Highlight-Language header will be set to the encryption scheme.

?a=: optional. Set Content-Disposition to attachment if present.
?mime=<mime>: optional. Specify the mime-type, suppressing the effect of <ext>. No effect if lang is specified (in which case the mime-type is always text/html).

Examples: GET /abcd?lang=js, GET /abcd?mime=application/json.

HEAD `/*`

Request a paste without returning the body. It accepts same parameters as all GET requests, and returns the same Content-Type, Content-Disposition, Content-Length and cache control headers with the corresponding GET request. Note that the Content-Length with /a/<name>, ?lang=<lang> is the length of the paste instead of the length the actuala HTML page.

POST `/`

Upload your paste. It accept parameters in form-data:

c: mandatory. The content of your paste, text of binary. It should be no larger than 10 MB. The filename in its Content-Disposition will be present when fetching the paste.
e: optional. The expiration time of the paste. After this period of time, the paste is permanently deleted. It should be an integer or a float point number suffixed with an optional unit (seconds by default). Supported units: s (seconds), m (minutes), h (hours), d (days). For example, 360.24 means 360.25 seconds; 25d is interpreted as 25 days. The actual expiration might be shorter than specified expiration due to limitations imposed by the administrator. If unspecified, a default expiration time setting is used.
s: optional. The password which allows you to modify and delete the paste. If not specified, the worker will generate a random string as password.
n: optional. The customized name of your paste. If not specified, the worker will generate a random string (4 characters by default) as the name. You need to prefix the name with ~ when fetching the paste of customized name. The name is at least 3 characters long, consisting of alphabet, digits and characters in +_-[]*$=@,;/.
p: optional. The flag of private mode. If specified to any value, the name of the paste is as long as 24 characters. No effect if n is used.
encryption-scheme: optional. The encryption scheme used in the uploaded paste. It will be returned as X-PB-Encryption-Scheme header on fetching paste. Note that this is not the encryption scheme that the backend will perform.
lang: optional. The language of the uploaded paste for syntax highlighting. Should be a lower-case name of language listed in highlight.js documentation. This will be returned as X-PB-Highlight-Language header on fetching paste.

POST method returns a JSON string by default, if no error occurs, for example:

{
  "url": "https://shz.al/abcd",
  "manageUrl": "https://shz.al/abcd:w2eHqyZGc@CQzWLN=BiJiQxZ",
