HAR-Capture API Reverse Engineering

Turn a website's hidden/undocumented API into a verified, reusable client by capturing real browser requests to a HAR file, then deriving and replaying them — instead of reverse-engineering by trial and error against a "hidden" endpoint.

When to use

• A site you can operate in a browser has no documented API (or none is known) and you need an agent to call its backend directly instead of driving the UI.
• You need the exact request shape (method, URL, headers, JSON body) of an action rather than guessing by trial and error.
• A browser-only workflow is repeated often enough that a verified programmatic shortcut beats manual steps every time.
