Apicast

Apicast is the core API gateway component of the 3scale API Management platform. It is a high-performance, Nginx-based proxy that processes and controls all inbound API traffic. It intercepts requests, authenticates them against defined policies (like rate limits, access keys, or JWTs), and routes them to the correct upstream service. It’s designed to be deployed as a container, managing the secure and observable flow of communication between API consumers and backend services.
