Pangram

API

API that detects AI-written and AI-assisted text, with plagiarism checks

Price: Prepaid credits, pay per word
Access: API key (x-api-key)

About

Pangram's REST API scores how much of a text is AI-generated, AI-assisted or human, segment by segment, and a separate endpoint checks text for plagiarism against online content. Prepaid credits from $5; detection scores are the vendor's model estimates, not proof.

What you can do with it

Flag essays or submissions that were likely written by ChatGPT or another LLM
Show which passages of a document are AI-generated, AI-assisted or human-written
Check student or freelance writing for plagiarism against online sources

Get started

Create an API key and add credits in the Pangram dashboard
Submit text to POST /task, then poll GET /task/{task_id}

Example

curl -X POST https://text.external-api.pangram.com/task \
  -H "Content-Type: application/json" \
  -H "x-api-key: $PANGRAM_API_KEY" \
  -d '{"text": "The text to analyze", "model": "pangram-4"}'
