Disclosed embodiments are directed at systems, methods, and architecture for providing microservices and a plurality of APIs to requesting clients. The architecture is a distributed cluster of gateway nodes that jointly provide microservices and the plurality of APIs. Providing the APIs includes providing a plurality of plugins that implement the APIs. As a result of a distributed architecture, the task of API management can be distributed across a cluster of gateway nodes. The gateway nodes effectively become the entry point for every API-related request. Some embodiments of the disclosed technology describe an auto-documentation plugin that can automatically generate documentation for an API by monitoring, parsing, and sniffing requests/responses to/from the API.
