PlagiarismCheck.org API

Introduction

This document provides all the necessary information you need for checking texts for plagiarism in your application.

You can visit our GitHub profile to find more examples.

There are 2 kinds of APIs in PlagiarismCheck. The first API is for clients who will use the API as individual users. The second API is for organizations that include many users.

Both of the API types use an API-token for authorization, so you will need to contact your administrator or the support team to receive the API token first.

Here is a GitHub repository with examples, both for individual and organization APIs.

Also, you can check a Swagger page with API specification.

Sequence

To check a text for plagiarism in your application, you MUST:

  1. 1) Receive an authorization API token.
  2. 2) Send the text by using the API method and receive an identification number of the text.
  3. 3) Wait until we check the text.
  4. 4) Check the status of the text by using the ID from 2 and the API method. If the text is not checked, go to step 3 with timeout.
  5. 5) Receive a report by using the text ID from 2 and the API method.
  6. 6) Render the json report in your application.

Authorization

For authorization, you MUST have a registered account with PlagiarismCheck.org and a special API token from our support team.

To receive an API token, you need to contact our Support. Also, you can sign in and copy the actual API token below.

API returns 401 Unauthorized if you provide an invalid token. You MUST send your token in the header with the name X-API-TOKEN.

Example of an HTTP header:

X-API-TOKEN: vsMKX3179tjK3CqvhE228IDeMV-eBBER

Where vsMKX3179tjK3CqvhE228IDeMV-eBBER is an example of the api token.

Send the request

The request has parameters:

  • language - language of the text. At the moment, we support only one value: en.
  • text - content of the text you want to check. It MUST NOT be shorter than 80 characters.
The Request: 
curl "https://plagiarismcheck.org/api/v1/text"  \
 --request POST \
 --header  "X-API-TOKEN: cUwhcQU88K2cYn47aPCg-snWoSNNJwyW" \
 --data    "language=en" \
 --data    "text=an application programming interface (API) is a set of subroutine definitions, protocols, and tools for building application software. In general terms, it is a set of clearly defined methods of communication between various software components. A good API makes it easier to develop a computer program by providing all the building blocks, which are then put together by the programmer. An API may be for a web-based system, operating system, database system, computer hardware or software library. An API specification can take many forms, but often includes specifications for routines, data structures, object classes, variables or remote calls. POSIX, Microsoft Windows API, the C++ Standard Template Library and Java APIs are examples of different forms of APIs. Documentation for the API is usually provided to facilitate usage"

Sequence

To check a text for plagiarism in your application, you MUST:

  1. 1) Receive an authorization API token.
  2. 2) Send the text by using the API method and receive an identification number of the text.
  3. 3) Wait until we check the text.
  4. 4) Check the status of the text by using the ID from 2 and the API method. If the text is not checked, go to step 3 with timeout.
  5. 5) Receive a report by using the text ID from 2 and the API method.
  6. 6) Render the json report in your application.

Authorization

For authorization, you MUST have a registered account with PlagiarismCheck.org and a special API token from our support team.

To receive an API token, you need to contact our Support. Also, you can sign in as owner and copy the actual API token below.

Send the request

The request has parameters:

  • author - Username (email) of an organization member. This member will be the author of the check.
  • group_token - the API token
  • text - The text to be checked. Also, you can send a file (doc, docx, pdf, txt, odt, rtf) as shown in the example.
The Request: 
curl "https://plagiarismcheck.org/api/org/text/check/"  \
 --request POST \
 --data    "group_token=G-HEfFiCHYWYx...." \
 --data    "author=example@example.com" \
 --data    "text=an application programming interface (API) is a set of subroutine definitions, protocols, and tools for building application software. In general terms, it is a set of clearly defined methods of communication between various software components. A good API makes it easier to develop a computer program by providing all the building blocks, which are then put together by the programmer. An API may be for a web-based system, operating system, database system, computer hardware or software library. An API specification can take many forms, but often includes specifications for routines, data structures, object classes, variables or remote calls. POSIX, Microsoft Windows API, the C++ Standard Template Library and Java APIs are examples of different forms of APIs. Documentation for the API is usually provided to facilitate usage" \
