Cloudmersive vs Perspective

Cloudmersive's Image Recognition API covers captioning, face detection and recognition, and NSFW content classification behind a single API-key-based REST endpoint. CORS is fully open (a wildcard Access-Control-Allow-Origin), and the free tier includes 600 calls per month with no expiration before tiered Small Business, Medium Business, and Enterprise plans at custom pricing.

Perspective API, built by Google's Jigsaw team, scores text for toxicity, insults, threats, and related attributes using ML models trained on human-rated comments, returning probabilities from a JSON REST endpoint (commentanalyzer.googleapis.com). It's free and quota-gated rather than metered, but Google has announced the service will be shut down after 2026 and is only accepting quota-increase requests through February 2026. New integrations should plan for a different moderation provider before then, since Google has said it won't offer direct migration support.
