Envoy Proxy Rate Limit Service API is one of 25 APIs that [Envoy Proxy](https://apis.io/providers/envoy-proxy/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include gRPC, Proxies, Rate Limiting, and Service Mesh. The published artifact set on APIs.io includes API documentation, an API reference, and a GitHub repository.

The Envoy Rate Limit Service (RLS) is a gRPC-based API that allows Envoy to delegate rate limiting decisions to an external service. When a request matches a configured rate limit rule, Envoy calls the RLS to check whether the request should be allowed or throttled based on descriptors extracted from the request context.
