For business customers: The self-service API is available to verified business accounts. You buy credits in advance, create your own API keys and keep track of usage and scan status in your customer account.

Plagiarism and AI in one API workflow

Every API order automatically includes a plagiarism check and an AI detection. One credit covers each started 250 readable words. A separate checking mode is not required.

The API accepts DOC, DOCX, PDF, ODT, RTF, TXT and PAGES files up to 100 MB. After the technical pre-check, you receive the word count, the credit usage and a unique order ID. You then retrieve status and results through the API, or have them sent to a public HTTPS webhook address.

Typical uses

Your own web platform
Add plagiarism and AI checks to your SaaS product, submission portal or internal dashboard, under your own interface.
Learning and examination systems
Check submitted papers from an LMS, a university portal or a school workflow automatically, and match results to your internal ID.
CMS and editorial teams
Check articles, guest posts and agency copy for possible copying or AI patterns before publication.
Publishers and content teams
Build a consistent quality assurance process for manuscripts, whitepapers, studies and large text archives.

Ready in four steps

  1. Create a business account or set your existing account as a business account in your profile and confirm your email address.
  2. In the API tab, accept the terms, buy a credit package and generate an API key.
  3. Send the document with a unique Idempotency-Key to POST /api/v1/jobs .
  4. Retrieve status and result using the order ID, or process a signed webhook.

A short API call

curl -X POST https://corrected.eu/api/v1/jobs \   -H "Authorization: Bearer kd_live_YOUR_API_KEY" \   -H "Idempotency-Key: scan-order-4711" \   -F "file=@manuscript.pdf"

The idempotency key prevents a repeated request from booking the same order and the same credits twice. You can find the complete machine-readable description in the OpenAPI documentation.

Prepaid credits with full cost control

You buy scan capacity as simply as a prepaid balance. Credits do not expire and are only charged for accepted orders. If queueing or processing fails for good, the system refunds the reserved credits automatically.

Example: a document with 4,830 readable words needs 20 credits and receives both analyses for that. For larger volumes, individual rate limits or separate technical access, please contact us through the contact form .

Secure processing and clear retention

The transfer is encrypted. API keys are stored on the server only as a cryptographic hash. Webhook targets must be public HTTPS addresses, redirects are not followed, and outgoing webhooks are signed. Rate limits and atomic credit reservations protect your account and the platform against misconfiguration and duplicate processing.

The original file is deleted once processing is complete. Result data, protected report links and provided PDF files remain available for seven days. After that they are deleted or made inaccessible. The professional assessment stays with you: a technical percentage figure is a hint for review and is not, on its own, proof of unauthorised copying or AI generation.

Start with a verified business account, or open the technical API documentation directly.

Frequently asked questions about the Plagiarism/AI Scan API

Who can use the Plagiarism/AI Scan API?

The self-service API is enabled exclusively for verified business accounts. These include, for example, companies, publishers, universities, institutes, schools, agencies and other organisations.

How are credits calculated?

One credit covers each started 250 readable words. A text of 1 to 250 words needs one credit, a text of 251 to 500 words two credits. Plagiarism checking and AI detection are always included together.

Can we integrate the check into our own interface?

Yes. Your system uploads the document through the API and receives structured status and result data. Your users do not need to visit corrected.eu separately for this. You are responsible for lawful processing and for how results are displayed in your application.

How do we find out that a scan is finished?

You can query the status using the order ID, or give a public HTTPS webhook URL when creating the order. Webhook requests are signed so that your system can verify where they came from.

How long do results stay available?

Result data, protected report links and PDF files are available for seven days. The original file is deleted once processing is complete. Retrieve the results you need in good time.
