Code Plagiarism
Detection API

Build plagiarism detection into your apps. Check code against 20+ billion sources.

Documentation Get API Key

const response = await fetch('https://codequiry.com/api/v1/check', { method: 'POST', headers: { 'apikey': 'YOUR_API_KEY' }, body: formData }); // Check created!

UPDATE CHECK API

Update Check Details

Modify the name or programming language of an existing plagiarism check. Useful for correcting mistakes or updating check metadata before starting analysis.

API Endpoint

PATCH https://codequiry.com/api/v1/checks/{checkId}

POST https://codequiry.com/api/v1/check/update

Two equivalent forms: Use the RESTful path form (PATCH /checks/{checkId}) with the check ID in the URL, or the POST form (POST /check/update) with check_id in the request body. The name and language fields are sent in the body either way.

Authentication

Include your API key in the request header:

apikey: YOUR_API_KEY_HERE

Request Parameters

Parameter	Type	Required	Description
`checkId` (path) / `check_id` (body)	Integer	Required	The unique identifier of the check to update. Provide it as the `{checkId}` URL segment (REST form) or as `check_id` in the body (POST form).
`name`	String	Optional	New name for the check (3-255 characters)
`language`	Integer	Optional	New programming language ID (see Languages API)

Note: Both name and language are optional and may be sent together. If neither is provided, the request still returns 200 OK with the check unchanged.
