# Utility Detect AI Text API (https://www.socialcrawl.dev/platforms/utility/ai-detection)

> 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.

TL;DR: `GET /v1/utility/ai-detection` costs 1 credit per text. A call that cannot be scored right now (503) is not charged. and returns SocialCrawl's unified JSON schema. Single x-api-key auth, 100 free credits on signup.
