Humanverify Create
Get a HUMAN judgement on a subjective/culturally-nuanced question: we post the task to an account-free human rail, collect several answers, and return one typed verdict with an honest confidence (agreement × sample completeness). This create route returns a ticket immediately; poll the free result route for the verdict (human answers arrive asynchronously). Only judgement tasks are accepted — engagement/astroturf, captcha, PII and professional-advice tasks are rejected.
