operationId: audit_prose_forensics
summary: Forensic AI-trajectory & prose craft auditor
description: 'Deterministic prose forensics: word echoes within 50 words, repeated 3-6-grams, sentence-starter runs, hedge/filter/passive/nominalization density, burstiness, MATTR, Flesch-Kincaid, vocabulary fingerprints, AI syntactic tics (Not X. Y. pivots, verbless fragments, autonomous body parts), optional revision-history trajectory, and an editorial humanization map whose quotes are verified verbatim. Every finding has exact offsets and line:column. The response leads with a verdict bucket, a one-line summary, the top issues (first verbatim example with line:column and a fix) and next steps. English text only. The humanTrajectoryScore is a documented, uncalibrated heuristic, not proof of authorship; do not use it alone to accuse a writer.
Price: 1.00 USDC on Base (x402).'
