Cloudmersive vs TensorFeed
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.
TensorFeed is a free, no-auth JSON API for AI-industry data: real-time model pricing, provider status/outage monitoring (polled every 2 minutes), AI news, and agent-activity feeds, plus an in-browser API playground for every free endpoint. It also publishes an x402-based Premium Agent API (USDC on Base, no accounts or keys) for ranked model-routing recommendations, and self-certifies under its own "Agent Fair-Trade" standard with Ed25519-signed receipts and code-enforced no-charge on failed calls. Live-checked in July 2026: the site, its free endpoints, and CORS support are all confirmed working.
