Reverse-Engineering Hidden Web APIs

Logosofia no Dia a Dia · Aug 17, 2026 · 27m

Every web app you use exposes a hidden API layer through the HTTP requests your browser makes. This episode explores how to discover those undocumented endpoints, reverse-engineer them from network traffic, and wrap them into tools for AI agents. From simple copy-as-cURL endpoints to CSRF-protected workflows and request sequencing, we cover the taxonomy of hidden APIs, browser-agnostic approaches using mitmproxy, and the tradeoffs of building agent tooling on unsupported interfaces.
