What is The Profanity API?

The Profanity API is a context-aware, AI-powered moderation API for developers, built by indie developer Oleh Minko on Hono and Cloudflare. It screens user text for profanity by meaning rather than word lists.

The Profanity API is a moderation service aimed at developers who need to screen user-generated text for profanity and similar unwanted language. It is described by its creator as a context-aware, AI-powered API, which points to its main selling idea: judging words by how they are used instead of matching them against a fixed blocklist. That distinction matters for anyone who has dealt with the false positives and easy workarounds common to keyword filters. The project is built and published by Oleh Minko, a full-stack developer based in Winnipeg who builds products in public. It appears on his portfolio as the second featured project, listed with a live status and a stack that includes Hono and Cloudflare, plus one further technology not named on the page. A longer case study, dated January 2025 and rated at an 11 minute read, covers how the service was designed and built. The case study lists Cloudflare Workers and React among its technologies, which suggests an edge-hosted API paired with a web front end. In practice, a developer would integrate the service into an application that accepts comments, chat messages, reviews or profile text, send content to the API for assessment, and act on the result inside their own moderation flow. The homepage does not document endpoints, request formats, response fields, rate limits or supported languages, so those details have to be confirmed on the product's own site at the-profanity-api.com or in the case study. Among alternatives, the tool sits in the same space as general-purpose moderation endpoints from large AI providers and open-source word-list libraries. Its position is narrower and more focused: a dedicated profanity filter that leans on context. That makes it a candidate for small teams, indie developers and community platforms that want a single-purpose service without adopting a broad trust-and-safety suite. Buyers should treat it as an independent, solo-developer product and check its pricing, uptime commitments and support terms directly before relying on it in production.
