{"name":"ai-image-detector","description":"AI-generated image detector: send an image URL and get back a calibrated probability that the image is AI-generated or synthetic, plus the vision signals behind the score — anatomical artifacts (hands, teeth, eyes), garbled pseudo-text, over-smooth texture, lighting/shadow inconsistency, background incoherence, and an over-stylized 'AI look'. This is a vision-model heuristic, not a forensic or watermark-level detector, calibrated to never inflate a verdict just because a caller wants one. Verdict buckets: likely_real below 0.4, uncertain 0.4-0.65, likely_ai at 0.65+. A failed or unparseable vision call returns an error instead of a guess. Use it as an AI image detector, synthetic image checker, AI-generated picture screen, or image slop filter.","price":"$0.02","method":"POST","input_schema":{"properties":{"image_url":{"type":"string","description":"Direct HTTP/HTTPS URL to the image to assess."},"hint":{"type":"string","description":"Optional context about the image, e.g. 'profile picture' or 'product photo'.
