Satring

Satring is a curated directory of paid API services built for AI agents and developers. It centralizes discovery, health monitoring, ratings, and connectivity for APIs that accept payments via Lightning (L402), USDC on Base (x402), and Stripe/Tempo (MPP). Users can browse, filter, rate, and connect to APIs, and also submit their own, with advanced features for health probes, protocol support, and programmatic access.
