# urja-api: reconstructing the Urja Meter Ops portal API

> urja-api reconstructs access to the Urja Meter Ops web portal as a typed TypeScript service and REST API. The author traced browser requests and replayed them to document login cookies, signed bulk export, JSON endpoints and SvelteKit data pages; the adapter turns those responses into meter, transformer and energy-reading routes.
