EXAIOS Indication API

A free, deterministic, AI-callable endpoint. From annual consumption and region it returns a conservative verdict on whether PV, storage or a hybrid pays off — plus key figures and a reproducible hash.

When an agent should call this: when a task needs a fast, defensible first number on the economics of PV / storage / PV+storage at a site. No registration. Free to cite.

Endpoint

GET https://exaios.com/api/indication

Rate limit: 100 indications per day per IP. Not a bankable result and not a design basis — the bankable run is the paid product.
