openshield is a hosted API for moderation and fraud prevention, run by Sway SRL in Belgium. Send an image or a text from your server and get accept, review or reject, with the categories, scores and thresholds behind it: nudity, gore, weapons, hate symbols, hate speech, personal data, spam, scams and your own image categories. The same call checks what your users post and what your AI agents read and write. Send a sign-up, login or payment event and get allow, step up, hold or block, with the rules that fired; pack rules start in shadow and act on their own after a 30-day replay. Content is checked in memory and never stored. Built on openmod and openfraud, open-source Rust engines (Apache-2.0). Pay per check from a prepaid balance, with up to 2,000 free checks a month and no card.
