Utility Detect AI Text API
Returns how likely a text was written by an AI model: a calibrated probability, a level (likely, possible, unlikely or too_short) and the model name.

When to use the Utility Detect AI Text API
Use it to check one post, comment or passage you already have. To filter a whole page of posts, pass label=ai_written (and exclude=ai_written) on the post endpoint instead.
From the API reference
Pass one post, comment or passage as text (up to 8000 characters) and get back how likely it was written by an AI model, from SocialCrawl's own text classifier: p (0 to 1, calibrated), level (likely at p 0.95 or higher, possible at 0.71 or higher, unlikely below, or too_short for a text under 8 words, which carries p null) and model (the model name; a new name means a new scale). The model reads the opening of the text, about 1,000 characters. It is the same judgment post endpoints publish under label=ai_written, so a post checked here and on a list gets the same answer. It is a probability, not proof: a person can be flagged and an AI-written text can pass, and the shorter the text the less certain it is. Nothing is stored. 1 credit; a call that cannot be scored right now is a 503 and is not charged.

What can you do with the Detect AI Text API?
The Detect AI Text endpoint gives you structured Utility data with computed fields in a single request. No scraping infrastructure to build or maintain.
Example Request
# GET /v1/utility/ai-detection: 1 credit per call. Cache hits are free and failed calls are refunded.
# Check the price first for 0 credits: add dry_run=1 to the query. Nothing is fetched or charged.
# --max-time 60: the API's own time limit for this endpoint.
# --retry 3: retries timeouts, 429 and 5xx, honoring Retry-After.
# -o response.json keeps only the final attempt's body.
# One Idempotency-Key per request, reused on every retry, so a retried call is never charged twice.
