Auto-documentation for application program interfaces based on network requests and responses

A system for securing, managing, and extending functionalities of Application Programming Interfaces (APIs) in a microservices architecture, the system comprising:

• a plurality of APIs organized into a microservices application architecture;
• a processor operated control plane communicatively coupled to the plurality of APIs via data plane proxies, wherein the control plane is configured to:
• receive an incoming proxied request from a first API of the plurality of APIs directed to a second API of the plurality of APIs, the proxied request relayed to the control plane via a first data plane proxy associated with the first API;
• receive a proxied response from the second API, the proxied response relayed to the control plane via a second data plane proxy associated with the second API;
• parse the proxied request and the proxied response and extract current data;
• in response to a transaction that includes the request and the response, execute an auto-documentation plugin, wherein the auto-documentation plugin is configured to generate documentation based on the current data;
• and
• a data store configured to store the control plane and the documentation.
