Detect AI-generated text.

Detect if a passage of text is AI-generated.

Endpoint

POST https://api.bitmind.ai/detect-text

Request

curl -X POST https://api.bitmind.ai/detect-text \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"text": "In conclusion, the synergistic leveraging of cross-functional..."}'

JSON fields

Field	Type	Required	Description
text	string	Yes	The text passage to analyze
debug	boolean	No	Include debug data (raw score, processing time, region)
postContext	object	No	Optional source context (platform, source URL, author)

Requirements

Provide at least 200 characters of text. Shorter passages are rejected with 400 — there isn't enough signal to score reliably. English-language text scores best; unsupported languages or provider issues degrade gracefully to verdict: "uncertain".
