openshield is a hosted API for content moderation and fraud prevention, run by Sway SRL in Belgium. Send images or text from your server to receive an accept, review, or reject decision, along with the categories, scores, and thresholds behind it. Checks cover nudity, gore, weapons, hate symbols, hate speech, personal data, spam, scams, and custom image categories. The same API can check content that users post and that AI agents read or write. Send a sign-up, login, or payment event to receive an allow, step-up, hold, or block decision and the rules that triggered it. Pack rules begin in shadow mode and can act automatically after a 30-day replay. Content is checked in memory and is not stored. openshield is built on openmod and openfraud, open-source Rust engines licensed under Apache-2.0. Pricing is per check from a prepaid balance, with up to 2,000 free checks per month and no card required.
