File Uploader

The file uploader is implemented in the Python programming language using FastAPI. All uploaded files are stored on the server. The API provides the ability to preview and download files based on their file extensions.

New Feature!

Upload a .txt file containing only the full link to a resource to shorten it! (The service will automatically redirect you to the specified link when you follow a link to a txt file)

API Documentation

The API is currently hosted at fu.andcool.ru.
Page redirection is handled through the nginx proxy server. The API consists of 2 paths:

/file/ – Endpoint where all files are located.
/api/ – Main API endpoint

1.1 Authorization Errors

All requests requiring the Authorization header may encounter errors related to authorization issues.
The Authorization header should have the format Authorization: Bearer <token>.

Response Example

All errors of this type follow a consistent response format and always return an HTTP code of 401.
This section will be referred to as 1.1 in the documentation.

{
    "status": "error",
    "message": "Auth error",
    "auth_error": {
        "message": "error message",
        "errorId": <error code>
    }
}

List of errors:

errorId	message	Reasons
-1	No Authorization header provided	The request is missing the `Authorization` header
-2	Authorization header must have `Bearer <token>` format	The `Authorization` header has an incorrect format
-3	Access token expired	The token has expired
-4	Invalid access token	The token cannot be decrypted
-5	Token not found	The token is not found

1.2 Basic API

Retrieve a file based on the URL.

GET /file/<file_url> or GET /f/<file_url>
Successful execution returns a 200 status code and the binary file with the Content-Type.
If the file type cannot be determined, the API returns the file in download mode.

Possible Errors

Error Code	Description	Possible Reasons
404	File not found	The file referenced by the code does not exist

Upload a file to the server

POST /api/upload/{group_id}?include_ext=false
The request body should contain the file to be uploaded.
Only one file is allowed, and its size should not exceed 100MB.
The maximum request frequency is 2 per minute.

Query params:

The group_id parameter indicates the group to which the file should be uploaded. The parameter can take the value private, which means that the file must be linked to a personal account. When passing the group_id parameter other than the private Authorization header is required.

Request body:

The Content-Type header of the request must be a multipart/form-data
The file must be have file key in request body.
The query parameter include_ext can be set to true/false to indicate whether the file extension should be included in the file URL.

Request headers:

The request can also include the Authorization header, containing the user's unique token. If the token is not provided or is not valid, the synced field in the response body will be set to false. The file will be uploaded to the server regardless of whether the Authorization header is included in the request. The auth_error field in the response body contains the authentication error (section 1.1), and if there is no error, the field will be {}.

Response Example

On successful execution, the API returns a 200 HTTP code along with a JSON response.

{
    "status": "success",
    "message": "File uploaded successfully",
    "file_url": "4yn-8yjhsu",
